I start Thunderbird with the following script:
#! /bin/bash
export LC_TIME=en_DK.utf8 && thunderbird "$@"
For emails sent or received today only the time is shown, e.g., 13:17.
For emails sent or received more than a week ago, the year, month, day
and time are shown, e.g., 2018-06-13 07:43.
For emails sent and received a week after today only the year, month and
time are shown, e.g., 2018/06 19:53.
How do I get Thunderbird to use the same format for dates/times more
than a week old?
This problem appeared after upgrading from Jessie to Stretch with
Thunderbird 52.8.0 in Stretch. I used in Jessie the same script quoted
above, where all dates after today were 2017-03-28 23:19. (I do not
remember which version of Thunderbird I had in Jessie.)
