I have Edit > Preferences > Calendar > Timezone set to Europe/Moscow (same settings as for Ubuntu and Excnahge). Still I have current time in Lightning hour later then system time, while event are displayed correctly. Please suggest can I adjust Europe/Moscow timezone by myself? Thank you.

I think you should file a bug. My guess is no one is aware of the changes to the Moscow timezone and the data file used needs updating.

I have the same problem with Thunderbird 31.6.0 on Gentoo, which is the latest release as of the time of writing. But the Thunderbird trunk seems to have this fixed. Weird, since the timezone change occurred on 26th of October, about 7 months ago.

I've just tried to see if anyone has filed a bug report regarding the Moscow Time, but could not find one.

Please post a bug report using the link provided by Matt. If they are not told about the issue, they may not know.

Tell them your OS, version of Thunderbird and version of Ligtning etc. Give clear details about the issue.

After creating a bug report, post a link to the bug in this forum so anyone with similar issue can locate the information and follow progress.

I filed a bug yesterday, which was closed with the comment that the bundled timezones had been updated in Thunderbird 38.

Pastafarianist Many thanks for your update and bug report.

38 is actually a week over due for release, so I suggest you just install the beta if you can not wait for the official release.
