Such a difference would not be caused by a desynchronized clock on the 
reading computer, because the timestamp is an immutable value in the 
message, created when the message is written. The displaying computer 
may apply an offset based on the timezone it has configured, but that's 
always multiples of 30 minutes, and is independent of the current time 
on the computer. (E.g. you could set your computer's clock off by 7 days 
11 hours and 12 minutes, and the message's timestamp would still only be 
offset by less than 24 hours.)

Thomas' theory that it may be caused by the web frontend has some 
merits: It may be that the web frontend creates its own timestamp when 
it processes the message, and that may well be about 2 minutes after the 
message is originally posted via the NNTP protocol. So the web version 
of the replied-to post may have a different timestamp than the NNTP version.
