[ANNOUNCEMENT] [Updated] tzcode 2020b

[Brian Inglis]

The following package has been updated in the Cygwin distribution:

* tzcode 2020b

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.
It is updated periodically to reflect changes made by political bodies
to daylight saving (summer time) rules, UTC offsets, and time zone
boundaries.
This package provides the tzselect, zic, zdump utilities.

News for the tz utilities

Release 2020b - 2020-10-06 18:35:04 -0700

Briefly:

zic no longer supports -y, nor the TYPE field of Rules.

Changes to code

Support for zic's long-obsolete '-y YEARISTYPE' option has been
removed and, with it, so has support for the TYPE field in Rule
lines, which is now reserved for compatibility with earlier zic.
These features were previously deprecated in release 2015f.
(Thanks to Tim Parenti.)

zic now defaults to '-b slim' instead of to '-b fat'.

zic's new '-l -' and '-p -' options uninstall any existing
localtime and posixrules files, respectively.

The undocumented and ineffective tzsetwall function has been
removed.

The long-obsolete yearistype.sh has been removed from the distribution.
