Doc Text:
Previously, the rotatelogs utility did not correctly handle local time. Consequently, when using rotatelogs with a date format including "%Z", "%Z" was replaced by the timezone name, disregarding the daylight saving time. This bug has been fixed, and rotatelogs now expands the "%Z" variable in the date format correctly.

Description Luke Meyer 2013-03-18 16:28:54 UTC 
Description of problem:
At least right now, when I direct rotatelogs to put the timezone in the log file name, it does not appear to notice that DST is in effect.

Version-Release number of selected component (if applicable):
httpd-2.2.15-26.el6.x86_64
tzdata-2012j-2.el6.noarch

How reproducible:
Always (at least for now)

Steps to Reproduce:
1. ln -sf  /usr/share/zoneinfo/US/Eastern /etc/localtime (other DST zones will do as well)
2. date
3. echo 1 | rotatelogs '/tmp/foo-%Y%m%d-%H%M%S-%Z' 60
4. ls /tmp/foo*
  
Actual results:
2. Mon Mar 18 12:25:06 EDT 2013
4. /tmp/foo-20130318-162500-EST

Expected results:
4. /tmp/foo-20130318-162500-EDT

Reassigning to "apr". It's apr_strftime problem.

Comment 4 Joe Orton 2013-10-10 16:05:58 UTC 
Missed this one...

"rotatelogs -l" should do the right thing here.
Comment 5 Luke Meyer 2013-10-10 17:32:13 UTC 
Hmm, that doesn't appear to help, sorry.

# ln -sf  /usr/share/zoneinfo/US/Eastern /etc/localtime
# date

# echo 1 | rotatelogs -l '/tmp/foo-%Y%m%d-%H%M%S-%Z' 60
# ls /tmp/foo*
