Date/Time Older-Than N Seconds/Minutes/Hours/Days

Demonstrates the how to tell if a date/time is older than the current time by N seconds, minutes, hours, or days. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final dt = CkDateTime();

  // Set to the current system date/time.
  dt.setFromCurrentSystemTime();
  print('Now: ${dt.getAsTimestamp(true)}');

  // Subtract 10 minutes, making the date 10 minutes in the past.
  dt.addSeconds(-600);
  print('10 minutes ago: ${dt.getAsTimestamp(true)}');

  // Is the date/time older than 10 seconds?
  var b = dt.olderThan(10, 'seconds');
  print('Older than 10 seconds: $b');

  // Is the date/time older than 5 minutes?
  b = dt.olderThan(5, 'minutes');
  print('Older than 5 minutes: $b');

  // Is the date/time older than 15 minutes?
  b = dt.olderThan(15, 'minutes');
  print('Older than 15 minutes: $b');

  // Is the date/time older than 1 hour?
  b = dt.olderThan(1, 'hour');
  print('Older than 1 hour: $b');

  // Is the date/time older than 1 day?
  b = dt.olderThan(1, 'day');
  print('Older than 1 day: $b');

  // Output:

  // 	Now: 2017-05-05T23:33:06-0500
  // 	10 minutes ago: 2017-05-05T23:23:06-0500
  // 	Older than 10 seconds: True
  // 	Older than 5 minutes: True
  // 	Older than 15 minutes: False
  // 	Older than 1 hour: False
  // 	Older than 1 day: False
