Fixed In Version: rh-perl526-perl-DateTime-TimeZone-2.17-1.el7 Doc Type: Rebase: Bug Fixes Only
Doc Text:
The *DateTime::TimeZone* Perl module is now aware of recent time zone updates Previously, the Olson time zone database was outdated. As a consequence, applications written in the Perl language that use the *DateTime::TimeZone* module mishandled time zones that changed their specifications since version 2017c. The _perl-DateTime-TimeZone_ package has been rebased to version 2.17, and the Olson time zone database has been updated to version 2018c. As a result, the *DateTime::TimeZone* module is aware of all time zone updates until version 2018c.

rh-perl526-perl-DateTime-TimeZone-2.15-3.el7 delivers 2018b Olson database. There is new 2018c database provided within DateTime-TimeZone-2.16.
Comment 1 Jitka Plesnikova 2018-01-24 09:31:34 UTC 
The latest version is 2.17 and it provides 2018c Olson database.
Comment 2 Jitka Plesnikova 2018-02-01 12:51:43 UTC 
How to test:

(1) Use DateTime Perl object with time and time zone whose rules changed after releasing 2017c Olson database (bundled within the old perl-DateTime-TimeZone-2.15-3.el7 package) and before releasing 2018c Olson database (provided within the new perl-DateTime-TimeZone-2.17-1.el7 package). E.g. these commands:

$ scl enable rh-perl526 bash
$ perl -e 'use DateTime; my $d=DateTime->new(year=>2018,month=>1,day=>1,hour=>1,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}'

Before:
  2018-01-01T01:00:00+0000
After:
  2018-01-01T02:00:00+0100


(2) You can compare it with date(1) output that uses database from tzdata package:

  $ TZ=Africa/Sao_Tome date --date '2018-01-01T01:00:00+0000' '+%FT%T%z'
  2018-01-01T02:00:00+0100
