Hum ... the problem may be deeper than I thought.
My post above (to start the thread) shows as 2:36am here, but on the User Posts page, it reads "Thu, Mar 4th 2:4 AM".
I have some posts that are time-stamped "12:9 AM" on User Posts. The nine cannot be the tens part of the minute; it's either the single part of the minute, some sort of rounding, or a completely random number.
I have a post that shows up as "Feb 8th 12:57 AM 2004" on the actual post, and "Feb 8th 12:8 AM" on User Posts -- see
