.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the `DateTime::TimeZone` module mishandled time zones that changed their specifications since version 2017b due to the outdated database.

Description

2018-01-24 09:05:48 UTC
The latest version is 2.17 and it provides 2018c Olson database. perl-DateTime-TimeZone-1.70-1.el7 delivers 2017b Olson database Latest Olson database is 2018e. Latest Olson database is 2018f. 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/>. (In reply to Petr Pisar from comment #4) > perl-DateTime-TimeZone build script needs some adjustments, > see <https://lwn.net/Articles/771114/>. Actually <https://lwn.net/Articles/771115/>. 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. 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
