You mean the one's that said, "Posted Today, at 03:56" or "Posted 03-12-2006, at 19:32"? I used to use them to quickly check if a post had been made after I'd last visited. Now I've got to guess - if I last visited at five to an hour, and that was seven hours ago, then I'll also have to look through 55 minutes of posts that were made an hour ago to see if I read them, rather than looking for ones made at HH:55 and above.

Edit:

Oh, you mean my local time? I didn't, no. Haven't really bothered with my local time for a week or two - just using post times in relation to each other.
