Incoherent info in 'Last edited' column on translation list

The 'Last edited' column in the language list of each project shows the time zone data (GMT) but there's no need on it, because no time data is showed with the date.

Introduction:

When you see an available translation list in a product, ( i.e. https://launchpad.ubuntu.com/rosetta/products/encfs ), you can see the 'last edited' tag on the list, wich is composed of a date and the string 'GMT' ( i.e. : '2005-04-12 GMT' ).

Bug:
The string GMT is irrelevant if you don't have any time in the 'last edited' tag, 'cos it makes no difference in the info.

So:
The string 'GMT' must be removed, or may be the time of the last change, added to the string.
