#23 edit timestamp always shows 12h format

[Dominic Frohlof]

there is something wrong with edit timestamp in admin
panel.

when editing, it will alwas show the hours in 12 hour
format at first, e.g. 20 will become 8.

saving a '20' works, though.

this is solved in the 0.7.5 release we are working on right now.
