Hello Ben,

The "standard-JS" windows-object isn't available to our readers.

But FSK features a <global>Timer
Like used here in Fskin.dialog.autoClick taken from fskin.so

Spoiler:

this.Fskin.dialog.autoClick = function (name) {
var button;
if (name in this.sandbox) {
button = this.sandbox[name];
if (button.visible && button.active) {
button.state = 3;
button.invalidate();
this.autoClickTimer = new <global>.Timer();
this.autoClickTimer.onCallback = this.autoClickTimerCallback;
this.autoClickTimer.target = button;
this.autoClickTimer.schedule(250);
}
}
};
this.Fskin.dialog.autoClickTimerCallback = function (delta) {
var button;
button = this.target;
button.state = 1;
button.invalidate();
button.select();
};

I havn't check yet, if Timer is scriptable or had to be addressed in compiled code.
Maybe this can set you on track.
PS: <global> has not to be typed in!
PPS: take care to cancel() and delete the Timer properly, as a active Timer may prevent suspend-mode and thus drain the battery.
