In UTC-0700, it's 6 hours behind. br...@neon:~$ date; date -d"a fortnight ago"; date -d"14 days ago" Sat May 29 15:55:48 PDT 2010 Sat May 15 09:55:48 PDT 2010 Sat May 15 15:55:48 PDT 2010 br...@neon:~$ (export LC_ALL=C; date; date -d"a fortnight ago"; date -d"14 days ago) Sat May 29 15:56:02 PDT 2010 Sat May 15 09:56:02 PDT 2010 Sat May 15 15:56:02 PDT 2010 I guess "a fortnight ago" is doing something weird with the UTC-0100 timezone. Two servers running lenny (one with the same UTC-0700 timezone, another with UTC+0000) don't have this bug. Brian
