Please provide feedback on these changes in this test release if splitting the
tzdata packages as described may have a negative impact on your system.

The following test packages have been uploaded to the Cygwin distribution:
* tzdata 2024a-2
* tzdata-right 2024a-2
* tzdata-posix 2024a-2
This Cygwin test release splits out the likely rarely used "right"
and "posix" subtrees from mandatory base /usr/share/zoneinfo into their
own optional packages tzdata-right and tzdata-posix.
Tests checking for missing or invalid representative zones in all parts
of the base, posix, and right subtrees has been added as part of the
package definition script.
Please test this base package and report any issues, and let us know if
you need to install and use the zones in the "right" or "posix" subtrees
in the optional tzdata-right and tzdata-posix packages, and whether this
change causes any issues for you.
If there are no reports of issues, all future tzdata updates will be
split into three packages, and only the base tzdata package installed by
default on all systems.
The space occupied by installed files, and downloaded from mirrors, is
shown below for each package, plus the current package with all zones.
install tar tzdata
721KB 172KB base

The Time Zone Database (often called tz, tzdb, or zoneinfo) contains
data that represents the history of local time for many locations around
the world, and supports conversion of UTC time to local time at those
locations to allow display of those local times. It is updated
periodically to reflect changes made by political bodies to summer
daylight saving time rules, UTC offsets, and time zone boundaries.
Three data packages are available: base 'tzdata' is always installed;
optional 'tzdata-right' provides TAI-10s time in the 'right' subtree;
and optional 'tzdata-posix' provides the same zones and times as base
data in the 'posix' subtree, as an explicit distinction from 'right'.
The tzcode package provides the tzselect, zdump, and zic utilities.
