Example

Suppose we place the following code on frame 10 of a movie:

time1 = new Date();

Then we place the following code on frame 20 of a movie:

time2 = new Date();

elapsedTime = time2.getTime() - time1.getTime();

Note that Flash’s global getTimer() function also gives us access to elapsed time in a movie.

returns the value 240 (240 minutes is 4 hours):

myDate = new Date();

trace(myDate.getTimezoneOffset()); // Displays: 240

However, when invoked in EDT, during non–daylight savings times of year, the same code

returns 300 (300 minutes ...
