xenix on 6300

[C. Hergenhan]

the 6300 (unlike the basic ibm/pc) has a clock
which runs when power is off.  when i bring up
the at&t version of ms/dos on the 6300, the
date and time are always correct.  i'm told at&t
modified ms/dos to know about this perpetual
clock.  i'm also running xenix 3.0 on my pc and
would like to have the date and time set correctly,
but alas xenix is unaware of the 6300's clock.
anyone know a way to get at this clock from xenix?
thanks.... clem hergenhan, bell labs nj, 201-564-2118
