Misleading results Rated 1 out of 5 stars

A very useful add-on only let down by the fact the "GMT" option doesn't work. It always displays the result in local time.

E.g. 1342310400 displays
"July 15, 2012 01:00:00 (GMT+1)"
(correct) when "Use my local timezone" is selected but it displays
"July 15, 2012 01:00:00 GMT"
(wrong) when "Use GMT" is selected for the same epoch time.

c.f. "date -ud @1342310400" which gives "Sun Jul 15 00:00:00 UTC 2012"

Because this is misleading I've given this (otherwise useful) add-on only 1 star.
