The time shown in the Date column for TB is 2 hrs earlier than the actual time. The TB error console also displays the wrong time.

TB 128.6.0esr on freebsd-13.4-RELEASE-p5

System time is set to and displays as MDT (US Mountain/Denver) $ date Fri Apr 18 12:29:52 MDT 2025

TB error console: Date() "Fri Apr 18 2025 10:31:04 GMT-0800 (GMT-08:00)"

about:config timezone settings: calendar.timezone.local MST calendar.timezone.recent [] calendar.timezone.useSystemTimezone true mailnews.sender.date_senders_timezone false

Mail headers show proper time in mail file: Received: from mail-yb1-f187.google.com (mail-yb1-f187.google.com [209.85.219.187]) ... for <xxx>; Fri, 18 Apr 2025 11:55:40 -0600 (MDT) Received: by mail-yb1-f187.google.com with SMTP id 3f1490d57ef6-e5740c858besf2902470276.2 ... for <xxx>; Fri, 18 Apr 2025 10:55:39 -0700 (PDT)

And display properly in the TB headers display: Date Fri, 18 Apr 2025 11:55:29 -0600

Yet TB displays 2 hrs earlier in the Date column: 09:55

How to correct? I had set the Calendar timezone manually, but it is now set as above. I tried deleting calendar.timezone.local but it is rewritten when TB exits.

what does your operating system return as the content of the TZ variable? What shows in the Date: header of the messages, that is the critical item here not the various received headers.

Thanks for the reply, sorry I left out the Date header.

The TZ environment variable is not set.

The Date: header is 2 hrs past the date displayed by TB, e.g.:

Date Sun, 20 Apr 2025 16:44:10 +0000

but TB shows:

04/20/2025 08:44 (should be 10:44, UDT-6 for MDT)
