Hey Andy,

Do you know if the phrase "Pre-init timestamp" is defined by some spec
(maybe outside of the IPMI one)?  I remember seeing that ipmitool
outputs this when the timestamp is 0, but is this really the right
phrase or just what an ipmitool coder picked?  I do agree that perhaps a
"Uninitialized" or atleast something else should be output instead of
01-Jan-1970.
