Try this on your root:
Code:
stop();
_root.onLoad = function() {
var timeNow = new Date();
hours = timeNow.getHours();
if (hours >= 0 && hours < 6) {
gotoAndPlay('Scene 2', 1)
} else if (hours >= 6 && hours < 12) {
gotoAndPlay('Scene 3', 1)
} else if (hours >= 12 && hours < 18) {
gotoAndPlay('Scene 4', 1)
} else if (hours >= 18 && hours < 24) {
gotoAndPlay('Scene 5', 1)
}
}
Change the
scene names to match yours, of course.
EDIT: And I suppose change the hours to suit your needs too.

I assumed 4 different times, but I see you have 5 scenes.
