Just as a followup to my own question - it looks as if the value being
used for the chat timeout is about 100 times too small. I don't know if
this means other timeouts are calculated incorrectly as well. Maybe the
calculation of TICKUNIT or SECTICKS is being done wrong in timer.h?

Obviously, I can't have gone through (650-521.8) seconds in between the
two timestamps (18:34:35 and 18:34:36). At any rate, if anyone else is
running into this problem, a user workaround is to put an insanely huge
timeout in your chat script. Mine is currently 6500 (which should be
nearly forever, but appears to be around 6.5 seconds).
