http://kb.mozillazine.org/Date_display_format shows how to configure the
date and time format for Thunderbird, though this also affects the
date/time that are displayed in the folder table-of-contents pane.  On
Linux, it looks like your options are limited.  I ended up using a
wrapper script for Thunderbird that does

  LC_TIME=en_DK.utf8 thunderbird

so that I get ISO-format dates.
