After upgrading Thunderbird client to version 114.4.1 on my Windows 10 computer, I no longer can see events. I am using a CalDAV server on Linux. I believe creating and updating events works on a different Linux client, but not on this Windows 10 client. In my error console I see the message, "Calendar: Could not find definition for Eastern Standard Time". I've read some posts where others had that same time zone issue and fixing that got their events to show up. Unfortunately, they did say how they fixed it. Perhaps that is my problem as well. How do I resolve this error (to start with)?
