Incorrect time on Thunderbird

C H B

Since our clocks/time went back one hour last weekend, Thunderbird for Mac is displaying the incorrect time. It displays the time as 1 hour ahead, effectively hasn't accepted the time change. The system time is correct, and Thunderbird is set to read system time. I have also tried changing it to "set manually" to our location, it makes no difference. Any assistance greatly appreciated.

where exactly is the time being incorrectly displayed? email times are derived from the message that is received, not some local setting.

Matt, thanks for your reply. Both email times and calendar. I have attached a screenshot, you will Thunderbird calendar showing 8.30, whereas system time correctly showing 7.30. Regards,
