require 'chilkat'

dt = Chilkat::CkDateTime.new()

# Set to the current system date/time.
dt.SetFromCurrentSystemTime()
print "Now: " + dt.getAsTimestamp(true) + "\n";

# Add 10 minutes, making the date 10 minutes in the future.
dt.AddSeconds(600)
print "10 minutes from now: " + dt.getAsTimestamp(true) + "\n";

# Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
b = dt.ExpiresWithin(10,"seconds")
print "Expires within 10 seconds: " + b.to_s() + "\n";

# Does the date/time expire within 5 minutes?
b = dt.ExpiresWithin(5,"minutes")
print "Expires within 5 minutes: " + b.to_s() + "\n";

# Does the date/time expire within 15 minutes?
b = dt.ExpiresWithin(15,"minutes")
print "Expires within 15 minutes: " + b.to_s() + "\n";

# Does the date/time expire within 1 hour?
b = dt.ExpiresWithin(1,"hour")
print "Expires within 1 hour: " + b.to_s() + "\n";

# Does the date/time expire within 1 day?
b = dt.ExpiresWithin(1,"day")
print "Expires within 1 day: " + b.to_s() + "\n";

# Output:

# 	Now: 2017-05-05T23:48:00-0500
# 	10 minutes from now: 2017-05-05T23:58:00-0500
# 	Expires within 10 seconds: False
# 	Expires within 5 minutes: False
# 	Expires within 15 minutes: True
# 	Expires within 1 hour: True
# 	Expires within 1 day: True
