+++ This bug was initially created as a clone of Bug #1536730 +++ Latest upstream release: 2.16 Current version/release in rawhide: 2.15-1.fc28 URL: http://search.cpan.org/dist/DateTime-TimeZone/ --- rh-perl526-perl-DateTime-TimeZone-2.15-3.el7 delivers 2018b Olson database. There is new 2018c database provided within DateTime-TimeZone-2.16.
The latest version is 2.17 and it provides 2018c Olson database.
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
