$This should be an easy one!  I have a standard, old 6 MHz IBM PC AT (believe
$it or not, but it keeps going), and I am trying to reset the system clock.
$The TIME command allows me to reset it for DOS (3.0) so as long as I leave
$the machine on I'm o.k., but when I turn it off, it comes back up with the
$same crummy incorrect time.  What's the trick to setting the actual hardware
$system clock?  The DOS manual says consult your GTO.  What's a GTO?

   It's a car, isn't it?  :-)

   But seriously, the DATE and TIME commands only affect DOS's clock, and
not the hardware clock available on ATs and higher (and as an add-in for
lower-end PCs).  At boot time, DOS sets its clock from the hardware clock;
from then on, however, DOS behaves as if the hardware clock didn't exist.

   Try looking through the disks that came with the AT; one of them should
include a program to allow you to set the system date and time (there should
be a disk that came with the AT rather than with DOS; that should be the one).

   Alternatively, "borrow" (ahem) a copy of one of the many setup programs
for ATs (e.g. Phoenix's SETUP that comes with ATs with a Phoenix BIOS) and
this will do the trick.

   (I must say I like BIOSes like Award and AMI which have the setup program
built-in, so you don't need to search through your 50 or 100 floppies for the
one with the setup program on it)
