In my experience, if the date is 0 then the clock chip isn't running at
all, and in that case a whole bunch of timeout-based things seem to
fall over. I've never tried doing networking when in that state, but
it wouldn't surprise me if clock interrupts weren't happening and hence
soft interrupts (soft network interrupts in particular) weren't
happening - which would break much of networking.
This "experience" is on a uVAX-II. (You mention a DEQNA, but that
merely means a Qbus VAX, not necesarily the uV2.)
