Solution 1

Strange thing to do!
Still...

VB

Dim ts As TimeSpan = DateTime.Now - New DateTime(1980, 1, 1)
Dim seconds As Double = ts.TotalSeconds

Solution 2

If you're storing the data in a database (based on your question title), I would strongly advice not to do that.

Instead store the date using a datetime column. You can always calculate the difference to a specific date using DATEDIFF[^]

Solution 3

Do not do such nonsense! Use the Date / DateTime datatype of your database instead.
