if we check the time only ever second we can get into trouble, eg:

assume its 12:34:56.99, displaying 12:34:56 takes some time and so its already
12:34:57 when we display 12:34:56. to fix that i set the time to check the
clock to 0.01 seconds. that shouldnt hurt much since we only redraw the clock
when the string has changed.

a more complex approach would be to analyze the strftime-string and set the
timeout accordingly. but i dont know if its really worth the effort and beeing
a bit off schedule can happen too, just not as often as if you are in seconds
mode.
