You'll have to tell us where you are getting that number from, 
and (possibly) what timestamp it should map to. From the size of it, 
I would guess it's the number of nanoseconds since some point of time.

The point in time it's coming from may be 1970-01-01, 1900-01-01, 
or something else (e.g. 1601-01-01). (Different computer systems 
store time differently). If it's the standard Unix epoch (1970) 
that corresponds to February 1990, if that helps.
