shckhead, shckcount are the variables for the dyn. text field in Layer 1 (Ebene
1).
With shckcount = Number(shckcount)-Number(1) we need not a further request of the
server time because we create with this function our own seconds-time.
Attention: we have to put the film-sequenze to 1 BpS!
The 'if-action' is for the condition of countdown <0, then we goto frame 1
and load the server data again because we have a new year variable!
