end of time

My favorite comment in the LJ codebase.

#   the end of time.  we don't include the last end of time second
#   because that's what backdated entries are set to.  (so for one
#   second at the end of time we'll have a flashback of all those
#   backdated entries... but then the world explodes and everybody
#   with 32 bit time_t structs dies)
