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. React Native

import { CkDateTime } from '@chilkat/react-native'

function chilkatExample() {
  const 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)?
  let 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
