Don,

I am not sure why you do not want to use the time() function, but if
you insist on counting ticks, you can peek4u(#46C), those four bytes
hold the number of ticks since midnight. The only advantage of this
method, apart from being probably much faster than the time() routine,
is that the update of the location is not apparently affected by the
tick_rate(). So you can have both, a finer resolution timer using a
suitable tick rate as well as your rough tick count - if you want to.
