They could be anything, but if they're OLE dates they're double-precision floating point values. The integer portion is the sequential day number since December 30, 1899, and the fractional part is the portion of the day since midnight: 0.25 is 1/4 of a day, or 6AM, etc.

Otherwise, you're going to have to post some data or show us how these are laid out. Give us several examples and, if possible, what dates you think they represent.
