Lubuntu Kinetic installation crashes near the end on a system with a badly outdated clock

Test hardware is on an HP Elitebook 8570p, 16 GB RAM, 120 GB SSD.

My Elitebook has a hardware problem that requires that I detach the CMOS battery and leave it that way in order for the system to function. Additionally, if I shut the system down, I have to leave it unplugged and with the battery removed, otherwise it won't boot when I go to turn it on next. (I think a thunderstorm fried a capacitor that had something to do with the CMOS, but anyway, weird as it may sound, that's the problem with my computer.)

As a result, when I power my Elitebook on, it thinks that it's some time in the year 2000, which is about 22 years off.

In addition, my Elitebook uses a Broadcom wireless chip, meaning that I have to connect to the Internet via Ethernet in order to install the driver for it. Since getting an Ethernet connection in my house is not so easy, I chose to simply perform the installation offline.

At the very end of the installation, the installation failed, and I received the following error message:

    External command finished with errors.

    Command apt-get update finished with exit code 100.

    E: Release file for cdrom://Lubuntu 22.10 _Kinetic Kudu_ - Alpha amd64 (20220514)/dists/kinetic/Release is not valid yet (invalid for another 18d 6h 51min 33s). Updates for this repository will not be applied.

The tar errors lead me to believe that this is a result of the out-of-date clock on my system. Furthermore, after connecting to the Internet to install the Broadcom drivers in the live environment and make the bug report, my clock is up-to-date, and I was able to install the system thereafter.
