If the sysplanar is changed or upgraded this problem always occurs. We
had on of the CPU cards fail in our R30 and after it came back up the
system clock was all zeroes (beginning of epoch - 00:00:00 on Jan 1
1970). The same thing after the 601 - 604 chipset upgrade. So, the
system didn't actually "change" the dat/time but read the
clock/calendar which had been reset to all zeroes, possibly from the
system crash or from a CE doing something weird.
