Hi Simon,

It looks from your code as if you have each hand animated in the timeline,
and are attempting to make it go to a specific point in the animation on
each frame.  One problem with this is that our export will add frames to
make animation run more smoothly.  The reason your minute and second hands
are only getting to 6 is because you are telling them to go up to 60 frames,
and apparently 60 frames only gets you to the 6.  If you count the seconds
that pass, it takes 30 seconds for the second hand to reach the 15.  So,
you've probably got twice as many frames as you think you have, and just
need to multiply by 2 in your code, or cut the keyframes in half in your
timeline.

Another thing I notice is you are calling "Number(hour+movement)".  Number
returns a boolean value (1 or 0), which means your hour is always going to
be 1 or 0.  This is why your hour hand is never going to move.

I've done a couple clocks in the past, and have found that the most
simplistic way to handle it is to make each hand a movieclip pointing at 12
when it's rotation is 0, and then in the onEnterFrame handler I put this
code...

var now = new Date();

_root.timers.hours._rotation = now.getHours() * 30 + (now.getMinutes() / 2);
_root.timers.minutes._rotation = now.getMinutes() * 6;
_root.timers.seconds._rotation = now.getSeconds() * 6;

In this example, "timers" is a group containing all 3 movieclips, "hours",
which is the mc of the hour hand, "minutes", "seconds", etc you get the
picture.

Sincerely,
Wil D.
