Does not have any example how to fix the date and time on a system with incorrect date and time..

xpbs-install -S chrony wouldn't work because the ssl cert was so far in the future..

Can we get an example of,

To set the date on a local system, where the local date and time is very out of sync..

date --set="20210316 14:10"

The would set the date to March 16th, 2021 and it is 2:10pm.

(then I could do xbps-install.. chrony.. etc..)

[root@voidME ~]# xbps-install -S chrony rsync

Also, my local network exports an ntp server and is running locally.. does the dhcpcd client not look for option 42?

You can use hwclock by the util-linux package which should be available already no matter how you installed Void since it's included in all base packages.

Great, I'll try that on the next one..

I'd still suggest getting "how to manually adjust the date" section to the Date-Time page in the docs..
