RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #1536730 +++

Latest upstream release: 2.16

----

perl-DateTime-TimeZone-1.70-1.el7 delivers 2018b Olson database. Latest Olson database is 2018c.
Comment 1 Jitka Plesnikova 2018-01-24 10:50:24 UTC 
The latest version is 2.17 and it provides 2018c Olson database.

perl-DateTime-TimeZone-1.70-1.el7 delivers 2017b Olson database
Comment 2 Petr Pisar 2018-09-27 10:28:33 UTC 
Latest Olson database is 2018e.
Comment 3 Jitka Plesnikova 2018-11-01 11:16:42 UTC 
Latest Olson database is 2018f.
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
