time zone settings

[cindyjj]

Thunderbird did not appear to correct itself when daylight savings time changed. I checked preferences/time and regional time zone was selected. Comparing the times emails were sent in the originating/third party account, those did correct with the dst change, but Thunderbird shows an hour later.

Thunderbird uses the operating systems time settings. If you look at the raw message source using control-U or view message source see what the Date: header says. The problem might be the sender didn't correct for daylight savings time. i.e. in Date: Sat, 27 Nov 2021 06:32:05 -0600 the -0600 might have been -0700.
