biostime() Return the Time of Day
#include <bios.h>

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.
