loDt = CreateObject('Chilkat.CkDateTime')

* Set to the current system date/time.
loDt.SetFromCurrentSystemTime()
? "Now: " + loDt.GetAsTimestamp(1)

* Add 10 minutes, making the date 10 minutes in the future.
loDt.AddSeconds(600)
? "10 minutes from now: " + loDt.GetAsTimestamp(1)

* Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
b = loDt.ExpiresWithin(10,"seconds")
? "Expires within 10 seconds: " + STR(b)

* Does the date/time expire within 5 minutes?
b = loDt.ExpiresWithin(5,"minutes")
? "Expires within 5 minutes: " + STR(b)

* Does the date/time expire within 15 minutes?
b = loDt.ExpiresWithin(15,"minutes")
? "Expires within 15 minutes: " + STR(b)
