VAX date stuck at year of 2010 #1053

In order for your system clock device to track consistently when you're not running VMS within the simulated system, you have to ATTACH it to a battery backup clock state container. Info about this is available via: |

however,how to make one data file to solve it,i don't have a real microvax3900 |
I don't understand this question. As I said earlier, your configuration file (should contain an ATTACH command for the CLK device which represents the battery backup for the clock chip on the original real hardware. If that system didn't have a battery installed, each time the system booted the date and time would have to be set manually. Once you have such an ATTACH command in the configuration used EACH time the simulator is started, the date and time will only have to be manually set the first time the system is booted and future reboots will behave as you expect. You might have to explicitly reset the date and time once every 16 or so months since the time is maintained in a 32bit register which updates once every 10ms and thus the value will wrap after about that time. A manual update of the time probably isn't needed for any OS which is rebooted more frequently than every 16 months. :-) FYI. The configuration file DOES NOT NEED Nice name: naY9yjoS6ZqhOd35sIFH Maybe you can make that a little bit more readable by adding your full name to your github profile. |

i am sorry ,i have read date(1) manpage,and made it |
i install simh from aur simh-git

the simulator configuration file (or commands) which were used when the problem occurred.
this is my configuration script for installation
cat nbsd.vax.inst.arch
load -r /usr/lib/simh-git/ka655x.bin
set cpu 256M
set cpu idle=netbsd
set rq1 cdrom
attach rq1 nbsdvax.iso
set rq0 rauser=16384
attach rq0 nbsdvax.img
attach nvr vax.nvr
attach xq0 nat:tcp=65533:10.0.2.15:22
boot cpu
the expected behavior and the actual behavior
and i install NetBSD 9.2 on simh-microvax3900
then the time is correct but date is back to 2010
cat nbsd.vax.arch
