Incorrect time (not in calendar)

I recently moved from the Eastern time zone to the Central time zone (US). I changed my computer’s time zone, but eM Client still thinks it’s in Eastern time. For example, the “last sync” time shows an hour ahead, and if I look at the log, it’s all an hour ahead as well. How can I change that?

eM Client version 7.0.26134.0

Does anyone have any ideas?
