Doc Type: Enhancement
Doc Text:
.The `DateTime::TimeZone` Perl module is now aware of recent time zone updates The Olson time zone database has been updated to version 2018i. Previously, applications written in the Perl language that use the `DateTime::TimeZone` module mishandled time zones that changed their specifications since version 2017b due to the outdated database.

Comment 4 Petr Pisar 2018-11-12 14:55:28 UTC 
Olson database 2018g changed tzdata format (added 25:00 time as discussed in bug #1646930). perl-DateTime-TimeZone build script needs some adjustments, see <https://lwn.net/Articles/771114/>.

Actually <https://lwn.net/Articles/771115/>.
Comment 6 Petr Pisar 2018-11-12 16:59:22 UTC 
Upstream DateTime-TimeZone-2.21 provides 2018g. 2.21 and 2.20 tools/parse_olson as well as lib/DateTime/TimeZone/OlsonDB* are the same. 2.20 supports 2018g.
Comment 9 Petr Pisar 2019-01-17 08:34:36 UTC 
We will provide update to the latest 2018i database.

How to test:

(1) Install "perl(DateTime)" and /usr/bin/perl.
(2) Print a 2019-01-01T00:00:00 UTC time for Africa/Sao_Tome zone. There was a change in 2018i database.
Before:
$ perl -e 'use DateTime; my $d=DateTime->new(year=>2019,month=>1,day=>1,hour=>0,minute=>0,second=>0,time_zone=>q{UTC}); $d->set_time_zone(q{Africa/Sao_Tome}); print $d->strftime(q{%FT%T%z}), qq{\n}'
2019-01-01T00:00:00+0000
After:
$ perl -e 'use DateTime; my $d=DateTime->new(year=>2019,month=>1,day=>1,hour=>0,minute=>0,second=>0,time_zone=>q{UTC}); $d->set_time_zone(q{Africa/Sao_Tome}); print $d->strftime(q{%FT%T%z}), qq{\n}'
2019-01-01T01:00:00+0100
(2) You can cross-check it with glibc:
$ TZ=Africa/Sao_Tome date --date '2019-01-01T00:00:00+0000' '+%FT%T%z'
2019-01-01T01:00:00+0100
