Can this actually be done?  I thought you had to accept the rate
of interrupts of the real time clock (which would be rather more
frequent than once a second).  On 286's and above you can use the
real clock alarm interrupt, but I don't know if there's any way to
accomplish the same thing on an 8086/88 machine.
