Here’s a quick example that is mentioned in the rationale of the commit: hardware that is offline and powered down for a significant amount of time. At boot, without an RTC (real time clock), it will have no idea of the current date or time. Most PCs have an RTC that will keep time for a while; if the time is wrong at power up, it’s not too big of a deal to fix it. For an embedded system, though, resetting the time could be a really big deal, especially if it is headless and had no continuous internet connection.
