Calendar: Could not find definition for W. Australia Standard Time

Hello,

I have the latest thunderbird (128.5.1esr (64-bit)), running on Windows 11 and connected to a mailcow server.

I am having problems with creating calendar events - they are created 1 hour in the future. They show up fine in thunderbird, but Mailcow/SOGo and mobile phones, etc all show the incorrect time.

If I create an event outside thunderbird, or edit it outside thunderbird, all is ok.

I have opened the error console, and it gives me a number of warnings "Calendar: Could not find definition for W. Australia Standard Time"

I am not sure where it is looking for this - but that is the timezone my computer is set to, it exists in the registry, etc.

There is an attached screenshot with more details of the error - maybe its java library issue or something?

Regards, Mal.

What do you have for the timezone in Settings/Calendar?

The settings in calender are set to windows .. it does the same if I set it to Austalia/Perth

However, if I use another timezone, eg Australia/Melbourne .. it works perfectly .. I put an event in and it appears at the correct time in SOGO, etc .. and if I change the timezone back to windows or Perth in the calendar settings, the event is correct.

It seems to be purely when creating a new event based on the Australia/Perth timezone :(
