' Add 10 minutes, making the date 10 minutes in the future.
success = dt.AddSeconds(600)
outFile.WriteLine("10 minutes from now: " & dt.GetAsTimestamp(1))

' Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
b = dt.ExpiresWithin(10,"seconds")
outFile.WriteLine("Expires within 10 seconds: " & b)

' Does the date/time expire within 5 minutes?
b = dt.ExpiresWithin(5,"minutes")
outFile.WriteLine("Expires within 5 minutes: " & b)

' Does the date/time expire within 15 minutes?
b = dt.ExpiresWithin(15,"minutes")
