From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have an old laptop running some basic services.
I have taken it apart before to replace the hard drive with an SSD, but I never replaced the dead CMOS battery because you have to literally completely disassemble it to get at the battery.
So I have a cronjob that runs on startup to change the system clock to the right time-zone.
It just felt simpler than completely disassembling a hard-to-take-apart laptop.
Debian (and Ubuntu) has the package "fake-hwclock". I'm sure other distros do too.
Periodically saves the time info to disk and resets the clock with it on boot.
