yeah, another way is to  determine the step-size used by timer and count
N changes... this works fine for dos but AIUI other platforms used different
step-sizes (this is the technique I use when I'm being lazy)

a more reliably accurate way is to use a generic formula

    tmp=(timer-timeout)
    if (tmp - 86400 * int (tmp / &H86400)) <  43200 then goto timeout
    '86400 is 24 hours, 43200 is 12 hours.

should work for timeouts upto 12 hours long...

    (I see Mike Ross has a similar formula...)

another way is to factor the date info the timer value used so that it
never goes backwards... then you can have any size of timeout you want.
