Thank you for your reply. As i looked at my data and what your SQL was doing, it doesn't appear that my numbers are stripped out time stamps. In one of the above posts a guy mentions that sometimes it's stored as the number of days since 1/1/1900. Do you know how to take a bigint like that and make it a normal date?
Here's some sample "dates" that i'm working with:
1196100822809
1196108435656
1196100810760
1196108412559
1196701846338
1196100817789
