Won,

That date is actually a 0 value, meaning 0 seconds since 1-Jan-1970.  
Most of the time, the BMC stays running on 5V standby power, but if the
BMC firmware restarts (e.g. after input power is lost or unplugged), it
starts over and starts its clock value at 0 until BIOS comes up and
gives it the real clock value.  
So, you'd expect to see a "Pre-init timestamp" in this case because the
SEL shows that the input power was lost.

Hey Won,

Well, I don't know if "normal" is the right phrase to use :-)  From my
experiences, many motherboards do report incorrect timestamps.  FreeIPMI
simply parses whatever information is on the motherboard.  So if it is
given a bad timestamp, it will output whatever that timestamp equates
to.
