DateTime to UnixTime Stamp in .net

{Edit} removed old reference link

Seconds since Jan 1, 1970 = unix time

To get this in VB.NET see below example (in example using DateTime.UtcNow, but you can plug in any DateTime you want there)

Dim uTime As Double
uTime = (DateTime.UtcNow - New DateTime(1970, 1, 1, 0, 0, 0)).TotalSeconds

I wrote these at some point - all similar to the above just with a little more detail on the old summer time adjustment thing for me here in the UK.

Public Function UnixToTime(ByVal strUnixTime As String) As Date
    UnixToTime = DateAdd(DateInterval.Second, Val(strUnixTime), #1/1/1970#)
    If UnixToTime.IsDaylightSavingTime = True Then
        UnixToTime = DateAdd(DateInterval.Hour, 1, UnixToTime)
    End If
End Function

Public Function TimeToUnix(ByVal dteDate As Date) As String
    If dteDate.IsDaylightSavingTime = True Then
        dteDate = DateAdd(DateInterval.Hour, -1, dteDate)
    End If
    TimeToUnix = DateDiff(DateInterval.Second, #1/1/1970#, dteDate)
End Function
