[Mailman-Users] Incorrect timezone in mailman-generated messages

[Ivan Kuznetsov]

Hello!

After the local timezone rules change the mailman sends messages with 
incorrect timezone in Date: header.

Acording to the Russian Govnerment statement Russia is abolishing 
daylight saving time from this year. E.g. Moscow time (which daylight 
saving was GMT+4) will now has standard GMT+4. To adopt this we install 
new timezone calculation rules (tzdata-2011l). Now the mailman thinks 
that timezone is GMT+3. All the mailman-generated messages (moderation 
requests, errors, reminders and so on) looks like the time is +1h in 
future. E.g.

Local time in mailman logs are still correct:

We are using mailman for years without such a problem before. All other 
software run at this host now have the correct understanding the local 
time as MSK standard time = GMT+4

[root at gate2 mailman]# date '+%Z %::z'
MSK +04:00:00

I found the similar mailman bug #266314 
(https://bugs.launchpad.net/mailman/+bug/266314) but it was years ago 
and was fixed at version 2.1.7.

Now we run mailman 2.1.14 with Python 2.4.3 under Oracle Enterprise 
Linux 5 (a clone of RHEL5)
