Rugster's post in Timestamps on Quotes was marked as the answer
It doesn't on mine, it's in the correct format. Is it something to do with your browser settings?
What's annoying is the original quote doesn't have a time on it, just a X hours ago or X minutes ago, when it goes past a day it just has the date. Can be annoying sometimes if you're reading something where the time of the post could be important (like reading back a Celtic in Europe thread to laugh at them).
