Apparently the box was reset on Friday. The hardware clock on the server is messed up so the time has to be set manually when this occurs. This accounts for all of the time-related problems people have been experiencing.
Does rdate adjust the system clock or the hardware clock?
I understood vroom to mean that the system clock is fine (likely uses NTP client) but the underlying hardware clock drifted waaaay off. This would only be a problem after power-cycle.
I have the same problem with a Debian box. Sometime I'll get around to cron'ing this: hwclock --systohc, which should keep the hardware clock from drifting so far.
