The current time as I was writing this is 16:21 (GMT+2) and for some reason 1:20:06 PM UTC appears as "21s ago" on SO. (The date is good, however.)
Isn't UTC = GMT? (1:20 pm UTC should be 3:20 GMT+2, giving a 1 hour offset meaning that 21 seconds ago should be 1 hour and 21 seconds ago.)
...I am probably missing something here.
