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. mike
