The number you have represents the number of seconds since Jan 1 1970.
So: 1075329297.572/(24*60*60)=12445 days

And from foxpro (01/01/1970) + 12445 = jan 28 2004

12445*86400=1075248000
Then 1075329297.572 - 1075248000 = 81297.572
81297.572/3600=22 hours
81297.572-(3600*22)=2097.572
2097.572/60=34 minutes
2097.572 - (34*60) = 47.572 seconds

End result Jan 28 2004 22:34:47.572
