Kevin,

Can you use datetime values instead? If so it's trivial.

declare integer Sleep in win32api integer nMillisec 

set hours to 24
ldFuture = datetime() + rand() * 24 * 60 * 60
do while datetime() < ldFuture
   @0,0 say "Time till done:" + ttoc( {^2003-1-1 00:00:00} + ( ldFuture - datetime() ), 2 )
   sleep( 1000 )
enddo
