Date/Time Expires Within N Seconds/Minutes/Hours/Days

Demonstrates the how to tell if a date/time is within N seconds, minutes, hours, or days of the current system time. Rust

let dt = chilkat::DateTime::new();

// Set to the current system date/time.
let _ = dt.set_from_current_system_time();
println!("Now: {}", dt.get_as_timestamp(true).unwrap_or_default());

// Add 10 minutes, making the date 10 minutes in the future.
let _ = dt.add_seconds(600);
println!("10 minutes from now: {}", dt.get_as_timestamp(true).unwrap_or_default());

// Is the date/time within 10 seconds of expiration (i.e. within 10 seconds of now)?
let mut b = dt.expires_within(10, "seconds");
println!("Expires within 10 seconds: {}", b);

// Does the date/time expire within 5 minutes?
b = dt.expires_within(5, "minutes");
println!("Expires within 5 minutes: {}", b);

// Does the date/time expire within 15 minutes?
b = dt.expires_within(15, "minutes");
println!("Expires within 15 minutes: {}", b);

// Does the date/time expire within 1 hour?
b = dt.expires_within(1, "hour");
println!("Expires within 1 hour: {}", b);

// Does the date/time expire within 1 day?
b = dt.expires_within(1, "day");
println!("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
