The problem of computer timekeeping lives on the margins. Your computer is probably more accurate than the quartz watch, but there's all sorts of ways that timekeeping can fail even on a system that's accurately counting time when on. Many of these have to do with early boot or unattended scenarios where trustworthy sources of time data are scarce or difficult to reach. e.g. maybe the motherboard clock chip is five months off because of a firmware bug or something, and this is a server so there's no user to notice the incorrect time and not having it set itself would cause catastrophic application failures somewhere else. Computer timekeeping is a comedy of errors.
