    biostime() either reads or sets the BIOS timer.  The timer is
    counting ticks since midnight at a rate of approximately 18.2 ticks
    per second.  If 'cmd' = 0, biostime() returns the current value of
    the timer.  If 'cmd' = 1, the timer is set to the long value in
    'newtime'.
 
    Returns:    If 'cmd' = 0, the timer's current value is returned.
