Your mistake is using new DateTime    which returns January 1  0001 at 00 00 00 000 instead of current date and time  The correct syntax to get current date and time is DateTime Now  so change this   String timeStamp   GetTimestamp new DateTime       to this   String timeStamp   GetTimestamp DateTime Now
