A bug in timer_interrupt() may have caused the system time to move up to two days or more into the future, or to be delayed for several minutes. This bug only affected Intel 64 and AMD64 systems that have the High Precision Event Timer (HPET) enabled in the BIOS, and could have caused problems for applications that require timing to be accurate.
