To convert a datetime string value like “YYYY-MM-DD HH:MM:SS” to a Unix timestamp (the seconds from 01/01/1970 to the input datetime) You can use a conversion function as the following:

Function ConvertToUnixTimeStamp(input_datetime) 'As String 
  Dim d
  d = CDate(input_datetime) 
  ConvertToUnixTimeStamp = CStr(DateDiff("s", "01/01/1970 00:00:00", d)) 
End Function

Then, to get back the datetime from the Unix timestamp use the following code:

Function ConvertUnixTimeStampToDateTime(input_unix_timestamp) 'As String [regular datetime] 
  ConvertUnixTimeStampToDateTime = CStr(DateAdd("s", input_unix_timestamp, "01/01/1970 00:00:00")) 
End Function
