Clock Error

I have been running my own build release on simh, as I am sure others may be
doing, after seeing such encouraging news that the VAX port may finally be
self-hostable again.  The build has not yet completed but is well along:

  PID USERNAME    THR PRI NICE   SIZE    RES STATE    C   TIME    WCPU COMMAND
 6963 sim312        1 145   10   199M   150M CPU0     0 110.6H 100.00% vax

I am now onto my 5th day running on the "classic" version of simh:

  VAX simulator V3.12-4

to which I added the small code fragment from open-simh for NEWBSD IDLE.

I did not add a network device and learned the hard way that you can't just
leave the default time after the install because some of the build config
fails when sanity checking the timestamps on files created.

So I set the system time from my watch (which is accurate to the second).

I just checked the date on the build box and compared it with another system.

My desktop:  Tue Dec 19 07:59:09 EST 2023
The Build:   Tue Dec 19 07:59:04 EST 2023

I am running a cross-compiled copy of 10.99.10 with the last GCC patch applied:

NetBSD nb10sim312 10.99.10 NetBSD 10.99.10 (GENERIC) #1: Mon Dec 11 09:17:31 EST 2023  netbsd@z440:/home/netbsd/obj/sys/arch/vax/compile/GENERIC vax

So for what it is worth, it appears I am loosing about one second per day,
on a 100% loaded simh session, after nearly five days running.
