Time in ActionScript
ActionScript provides support for working with dates and times through the Date
class. Here are some examples of how to use it:
package {
import flash.display.Sprite;
import flash.utils.getTimer;
public class TimeExample extends Sprite {
public function TimeExample() {
var p:Function = trace;
// We'll start by getting the current time.
var now:Date = new Date();
p(now);
// You can create a Date object by providing the year, month, day, etc.
// Note: Months are 0-indexed in ActionScript (0-11).
var then:Date = new Date(2009, 10, 17, 20, 34, 58, 651);
p(then);
// You can extract the various components of the date value as expected.
p(then.fullYear);
p(then.month);
p(then.date);
p(then.hours);
p(then.minutes);
p(then.seconds);
p(then.milliseconds);
p(then.timezoneOffset);
// The day of the week is also available (0-6, where 0 is Sunday).
p(then.day);
// These methods compare two dates, testing if the first occurs before,
// after, or at the same time as the second, respectively.
p(then.time < now.time);
p(then.time > now.time);
p(then.time == now.time);
// To get the difference between two dates, you can subtract their time values.
var diff:Number = now.time - then.time;
p(diff);
// We can compute the length of the duration in various units.
p(diff / (1000 * 60 * 60)); // Hours
p(diff / (1000 * 60)); // Minutes
p(diff / 1000); // Seconds
p(diff); // Milliseconds
// You can add or subtract time from a Date object.
p(new Date(then.time + diff));
p(new Date(then.time - diff));
}
}
}
To run this ActionScript code, you would typically compile it into a SWF file and run it in a Flash Player or AIR runtime environment. The output would be similar to the following:

Note that ActionScript uses the Date
class for working with dates and times, which is similar to JavaScript’s Date
object. It doesn’t have as many built-in methods for date and time manipulation as Go’s time
package, so some operations require manual calculation.
Also, ActionScript doesn’t have a built-in duration type like Go’s Duration
. Time differences are represented as numbers of milliseconds.
Lastly, ActionScript doesn’t have a concept of time zones built into the Date
class. All dates are created in the local time zone, and you can only get the offset from UTC.
