Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var dt = new CkDateTime();

// Set to the current system date/time.
dt.SetFromCurrentSystemTime();
console.log("Now: " + dt.GetAsTimestamp(true));

// Add 10 minutes, making the date 10 minutes in the future.
dt.AddSeconds(600);
console.log("10 minutes from now: " + dt.GetAsTimestamp(true));

// Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
var b = dt.ExpiresWithin(10,"seconds");
console.log("Expires within 10 seconds: " + b);

// Does the date/time expire within 5 minutes?
b = dt.ExpiresWithin(5,"minutes");
console.log("Expires within 5 minutes: " + b);

// Does the date/time expire within 15 minutes?
b = dt.ExpiresWithin(15,"minutes");
console.log("Expires within 15 minutes: " + b);

// Does the date/time expire within 1 hour?
b = dt.ExpiresWithin(1,"hour");
console.log("Expires within 1 hour: " + b);

// Does the date/time expire within 1 day?
b = dt.ExpiresWithin(1,"day");
console.log("Expires within 1 day: " + b);

// 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
