greetings Marzipanvernichter
Can't say this is something I've run into myself, personally.
If you click settings and go to calendar, is there possibly a different time zone selected there other than your system?
Do You have a Dual-Boot System? If Yes, did You set up the time for Dual-Boot?
i have only zorin at my computer
And did You checked @applecheeks37's Suggestion?
The time is in this days ok. i will look , sometimes in thunderbird comming wrong.
Thank you
