My post at 6:22 PM clearly quotes the subsequent post, which is timestamped at 6:24.
A server hiccup of some sort, perhaps? Or an incorrectly-set server clock?
Edited to add: I think that my timestamps may correspond to the system time on my computer. Should the posts reflect that time, or the FT server time?
