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.

Description Anton 2014-12-01 11:44:38 UTC 
Description of problem:
I use php-intl module which depends on libicudata.so
But libicudata.so has wery wery wery outdated timezone info, so any datetime functions form php-intl produces wrong output.

So could you rebuild the libicu package when the tzdata package is updated.


Version-Release number of selected component (if applicable):
libicu-50.1.2-11.el7.x86_64

How reproducible:
Everytime.

Steps to Reproduce:
1. Install php-intl
2. Update tzdata package
3. Run script:

<?php

$dateIn = '27.10.2014';
$tz = 'Europe/Moscow';
date_default_timezone_set($tz);
$intlDateFormatter = new \IntlDateFormatter('ru_RU', 2, -1, $tz, 1, 'dd.MM.yyyy');
$timestamp = $intlDateFormatter->parse($dateIn);

var_dump($intlDateFormatter->format($timestamp));
var_dump(date('d.m.Y', $timestamp));
?>

Actual results:
string(16) "27.10.2014"
string(16) "26.10.2014"

Expected results:
string(16) "27.10.2014"
string(16) "27.10.2014"

If this issue is critical or in any way time sensitive, please raise a ticket
through your regular Red Hat support channels to make certain it receives the
proper attention and prioritization to assure a timely resolution.
Comment 3 Eike Rathke 2014-12-02 11:33:19 UTC 
Need to figure out if the internal ICU timezone data actually can be updated without upgrading ICU.

However, I'm not even sure that the date decrement is due to outdated timezone data.

@Anton:
Could you verify that the specific date in that timezone given the procedure actually produces the desired result in environments that use a newer ICU?
Comment 4 Anton 2014-12-02 12:43:22 UTC 
@Eike:
I'll do.
For my mind, we can rebuild the current version of ICU with a new tzdata.

I'll try to rebuild the current version of ICU. If it will not help I'll try to build an updated version.
Comment 5 Anton 2014-12-02 18:47:13 UTC 
@Eike:

I've recompiled the current version of libicudata with new tzdata resources.
The how-to is here: http://habrahabr.ru/post/241447/ (on Russian, but translate.google.com can manage it.)

Recompilation solves the issue and I get the desired result. But I've found that libicu can be compiled with the data placed not in a shared library but in raw files on a file system.

In this case we can update only data files without a recompilation of a  library. But I don't know if this behavior has any issues.
Comment 6 Anton 2014-12-02 18:52:50 UTC 
P.S.: 
You have to have gcc-c++, icu, libicu-devel packages be installed.
Comment 7 Anton 2014-12-02 19:02:56 UTC 
>But I've found that libicu can be compiled with the data placed not in a shared library but in raw files on a file system.
libicu should be configured with PKGDATA_MODE=common in this case, default is PKGDATA_MODE=dll
Comment 8 Anton 2014-12-02 19:18:29 UTC 
Sorry, correct command is
./configure --with-data-packaging=(files|archive|library|static|auto)
where default is 'auto' which transforms to 'library' in libicu 50.1.2
Comment 9 Anton 2014-12-08 14:01:16 UTC 
There is a more general info about how to update tzdata here: http://userguide.icu-project.org/datetime/timezone#TOC-Updating-the-Time-Zone-Data
Comment 12 Mike FABIAN 2018-06-20 05:52:09 UTC 
This build fixes the problem:

https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=16792326

It updates the timezone data to 2018e and also adds the
negative-daylight-savings.patch from upstream (see
http://bugs.icu-project.org/trac/ticket/13566 and
http://bugs.icu-project.org/trac/changeset/40954)
Comment 13 Jens Petersen 2018-06-21 11:14:33 UTC 
Can you please file a separate bug for the negative daylight saving change?
Comment 14 Mike FABIAN 2018-06-21 14:43:58 UTC 
Here is a build without the extra patch for the negative daylight
savings offset:

https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=16817677

We don’t need that extra patch at the moment in RHEL-7.
Comment 15 Mike FABIAN 2018-06-25 08:24:43 UTC 
https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=16854122

Change pushed to the rhel-7.6 branch.
