(MSYS is no longer supported due to an outdated bash; While OpenJDK can be built with MSYS2, support for it is still experimental, so build failures and unusual errors are not uncommon.)</p>
 <p>Internally in the build system, all paths are represented as Unix-style paths, e.g. <code>/cygdrive/c/git/jdk/Makefile</code> rather than <code>C:\git\jdk\Makefile</code>. This rule also applies to input to the build system, e.g. in arguments to <code>configure</code>. So, use <code>--with-msvcr-dll=/cygdrive/c/msvcr100.dll</code> rather than <code>--with-msvcr-dll=c:\msvcr100.dll</code>.

+<h2 id="signing">Signing</h2>
+<h3 id="macos-1">macOS</h3>
+<p>Modern versions of macOS require applications to be signed and notarizied before distribution. See Apple's documentation for more background on what this means and how it works. To help support this, the JDK build can be configured to automatically sign all native binaries, and the JDK bundle, with all the options needed for successful notarization, as well as all the entitlements required by the JDK. To enable <code>hardened</code> signing, use configure parameter <code>--with-macosx-codesign=hardened</code> and configure the signing identity you wish to use with <code>--with-macosx-codesign-identity=&lt;identity&gt;</code>. The identity refers to a signing identity from Apple that needs to be preinstalled on the build host.</p>
+<p>When not signing for distribution with the hardened option, the JDK build will still attempt to perform <code>adhoc</code> signing to add the special entitlement <code>com.apple.security.get-task-allow</code> to each binary. This entitlement is required to be able to dump core files from a process. Note that adding this entitlement makes the build invalid for notarization, so it is only added when signing in <code>debug</code> mode. To explicitly enable this kind of adhoc signing, use configure parameter <code>--with-macosx-codesign=debug</code>. It will be enabled by default in most cases.</p>
+<p>It's also possible to completely disable any explicit codesign operations done by the JDK build using the configure parameter <code>--without-macosx-codesign</code>. The exact behavior then depends on the architecture.

 <h2 id="cross-compiling">Cross-compiling</h2>
 <p>Cross-compiling means using one platform (the <em>build</em> platform) to generate output that can ran on another platform (the <em>target</em> platform).</p>
 <p>The typical reason for cross-compiling is that the build is performed on a more powerful desktop computer, but the resulting binaries will be able to run on a different, typically low-performing system. Most of the complications that arise when building for embedded is due to this separation of <em>build</em> and <em>target</em> systems.</p>

+## Signing
+
+### macOS
+
+Modern versions of macOS require applications to be signed and notarizied before
+distribution. See Apple's documentation for more background on what this means
+and how it works. To help support this, the JDK build can be configured to
+automatically sign all native binaries, and the JDK bundle, with all the options
+needed for successful notarization, as well as all the entitlements required by
+the JDK. To enable `hardened` signing, use configure parameter
+`--with-macosx-codesign=hardened` and configure the signing identity you wish to
+use with `--with-macosx-codesign-identity=<identity>`. The identity refers to a
+signing identity from Apple that needs to be preinstalled on the build host.
+
+When not signing for distribution with the hardened option, the JDK build will
+still attempt to perform `adhoc` signing to add the special entitlement
+`com.apple.security.get-task-allow` to each binary. This entitlement is required
+to be able to dump core files from a process. Note that adding this entitlement
+makes the build invalid for notarization, so it is only added when signing in
+`debug` mode. To explicitly enable this kind of adhoc signing, use configure
+parameter `--with-macosx-codesign=debug`. It will be enabled by default in most
+cases.
+
+It's also possible to completely disable any explicit codesign operations done
+by the JDK build using the configure parameter `--without-macosx-codesign`.
+The exact behavior then depends on the architecture. For macOS on x64, it (at
+least at the time of this writing) results in completely unsigned binaries that
+should still work fine for development and debugging purposes. On aarch64, the
+Xcode linker will apply a default "adhoc" signing, without any entitlements.
+Such a build does not allow dumping core files.
+
+The default mode "auto" will try for `hardened` signing if the debug level is
+`release` and either the default identity or the specified identity is valid.
+If hardened isn't possible, then `debug` signing is chosen if it works. If
+nothing works, the codesign build step is disabled.

+# "Circular on Matching the Hours of Governmental and Official Circles

+# According to the ruling of the Honorable Cabinet, it is ordered that from

+# circles set their time to match Tehran time (three hours and half before
+# Greenwich)....
+#
+# I still haven't found out when Tehran itself switched to +03:30....
+#
+# From Paul Eggert (2022-06-05):
+# Although the above says Tehran was at +03:30 before 1935-06-13, we don't
+# know when it switched to +03:30.  For now, use 1935-06-13 as the switch date.
+# Although most likely wrong, we have no better info.
+
+# From Roozbeh Pournader (2022-06-01):
+# This is from Kayhan newspaper, one of the major Iranian newspapers, from
+# March 20, 1978, page 2:
+#
+# "Pull the clocks 60 minutes forward
+# As we informed before, from the fourth day of the month Farvardin of the
+# new year [=1978-03-24], clocks will be pulled forward, and people's daily
+# work and life program will start one hour earlier than the current program.
+# On the 1st day of the month Farvardin of this year [=1977-03-21], they had
+# pulled the clocks forward by one hour, but in the month of Mehr
+# [=1977-09-23], the clocks were pulled back by 30 minutes.
+# In this way, from the 4th day of the month Farvardin, clocks will be ahead
+# of the previous years by one hour and a half.
+# According to the new program, during the night of 4th of Farvardin, when
+# the midnight, meaning 24 o'clock is announced, the hands of the clock must
+# be pulled forward by one hour and thus consider midnight 1 o'clock in the
+# forenoon."
+#
+# This implies that in September 1977, when the daylight savings time was
+# done with, Iran didn't go back to +03:30, but immediately to +04:00.
+#
+#
+# This is from the major Iranian newspaper Ettela'at, dated [1978-08-03]...,
+# page 32. It looks like they decided to get the clocks back to +4:00
+# just in time for Ramadan that year:
+#
+# "Tomorrow Night, Pull the Clocks Back by One Hour
+# At 1 o'clock in the forenoon of Saturday 14 Mordad [=1978-08-05], the
+# clocks will be pulled one hour back and instead of 1 o'clock in the
+# forenoon, Radio Iran will announce 24 o'clock.
+# This decision was made in the Cabinet of Ministers meeting of 25 Tir
+# [=1978-07-16], [...]
+# At the beginning of the year 2537 [=March 1978: Iran was using a different
+# year number for a few years then, based on the Coronation of Cyrus the
+# Great], the country's official time was pulled forward by one hour and now
+# the official time is one hour and a half ahead compared to last year,
+# because in Farvardin of last year [=March 1977], the official time was
+# pulled forward one hour and this continued until the second half of last
+# year [=September 1977] until in the second half of last year the official
+# time was pulled back half an hour and that half hour still remains."
+#
+# This matches the time of the true noon published in the newspapers, as they
+# clearly go from +05:00 to +04:00 after that date (which happened during a
+# long weekend in Iran).
+
+# From Roozbeh Pournader (2022-05-31):
+# [Movahedi S. Cultural preconceptions of time: Can we use operational time
+# to meddle in God's Time? Comp Stud Soc Hist. 1985;27(3):385-400]
+# https://www.jstor.org/stable/178704
+# Here's the quotes from the paper:
+# 1. '"Iran's official time keeper moved the clock one hour forward as from
+# March 22, 1977 (Farvardin 2, 2536) to make maximum use of daylight and save
+# in energy consumption. Thus Iran joined such other countries as Britain in
+# observing what is known as 'daylight saving.' The proposal was originally
+# put forward by the Ministry of Energy, in no way having any influence on
+# observing religious ceremonies. Moving time one hour forward in summer
+# means that at 11:00 o'clock on March 21, the official time was set as
+# midnight March 22. Then September 24 will actually begin one hour later
+# than the end of September 23 [...]." Iran's time base thus continued to be
+# Greenwich Mean Time plus three and one-half hours (plus four and one-half
+# hours in summer).'
+#
+# The article sources this from Iran Almanac and Book of Facts, 1977, Tehran:
+# Echo of Iran, which is on Google Books at
+# https://www.google.com/books/edition/Iran_Almanac_and_Book_of_Facts/9ybVAAAAMAAJ.
+# (I confirmed it by searching for snippets.)
+#
+# 2. "After the fall of the shah, the revolutionary government returned to
+# daylight-saving time (DST) on 26 May 1979."
+#
+# This seems to have been announced just one day in advance, on 25 May 1979.
+#
+# The change in 1977 clearly seems to be the first daylight savings effort in
+# Iran. But the article doesn't mention what happened in 1978 (which was
+# still during the shah's government), or how things continued in 1979
+# onwards (which was during the Islamic Republic).

 # Lebanon
+#
+# From Saadallah Itani (2023-03-23):
+# Lebanon ... announced today delay of Spring forward from March 25 to April 20.
+#
+# From Paul Eggert (2023-03-27):
+# This announcement was by the Lebanese caretaker prime minister Najib Mikati.
+# https://www.mtv.com.lb/en/News/Local/1352516/lebanon-postpones-daylight-saving-time-adoption
+# A video was later leaked to the media of parliament speaker Nabih Berri
+# asking Mikati to postpone DST to aid observance of Ramadan, Mikati objecting
+# that this would cause problems such as scheduling airline flights, to which
+# Berri interjected, "What flights?"
+#
+# The change was controversial and led to a partly-sectarian divide.
+# Many Lebanese institutions, including the education ministry, the Maronite
+# church, and two news channels LCBI and MTV, ignored the announcement and
+# went ahead with the long-scheduled spring-forward on March 25/26, some
+# arguing that the prime minister had not followed the law because the change
+# had not been approved by the cabinet.  Google went with the announcement;
+# Apple ignored it.  At least one bank followed the announcement for its doors,
+# but ignored the announcement in internal computer systems.
+# Beirut international airport listed two times for each departure.
+# Dan Azzi wrote "My view is that this whole thing is a Dumb and Dumber movie."
+# Eventually the prime minister backed down, said the cabinet had decided to
+# stick with its 1998 decision, and that DST would begin midnight March 29/30.
+# https://www.nna-leb.gov.lb/en/miscellaneous/604093/lebanon-has-two-times-of-day-amid-daylight-savings
+# https://www.cnbc.com/2023/03/27/lebanon-in-two-different-time-zones-as-government-disagrees-on-daylight-savings.html
+#
+# Although we could model the chaos with two Zones, that would likely cause
+# more trouble than it would cure.  Since so many manual clocks and
+# computer-based timestamps ignored the announcement, stick with official
+# cabinet resolutions in the data while recording the prime minister's
+# announcement as a comment.  This is how we treated a similar situation in
+# Rio de Janeiro in spring 1993.

-# From Wikipedia <https://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
-# Before 1920, all ships kept local apparent time on the high seas by setting
-# their clocks at night or at the morning sight so that, given the ship's
-# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
-# meridian (12 o'clock = local apparent noon).  During 1917, at the
-# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
-# ships, both military and civilian, should adopt hourly standard time zones
-# on the high seas.  Whenever a ship was within the territorial waters of any
-# nation it would use that nation's standard time.  The captain was permitted
-# to change his ship's clocks at a time of his choice following his ship's
-# entry into another zone time - he often chose midnight.  These zones were

+# changes of longitude in one-hour steps.  The one-hour step corresponds to a
+# time zone width of 15° longitude.  The 15° gore that is offset from GMT or
+# UT1 (not UTC) by twelve hours is bisected by the nautical date line into two
+# 7°30' gores that differ from GMT by ±12 hours.  A nautical date line is
+# implied but not explicitly drawn on time zone maps.  It follows the 180th
