I know this one has already been answered. But I think I deal with something diferent.
I use an Ubuntu server 18.04 with mysql and a client with Windows 10 connecting with LibreOffice 126.96.36.199 (x64)
Everything was working fine when I got a message (probably caused by the summer time change):
“The Server time zone value ‘EEST’ is unrecognised or represends more than one time zone …”
Checked the windows client time zone is (UTC+02:00) and the Ubuntu Server timezone was EEST (Athens,Greece)
So I went to the LO (Edit/Database/Properties) and add to the database name instead of BusinessMonitor this: BusinessMonitor?useLegacyDatetimeCode=false&serverTimezone=Europe/Athens found from another similar post:
Checked the database connection and it worked saved the changes but the next time I tried to login instead of the full string the database name was just Athens saved and could not connect…
