Emacs doesn't need a precise boot time. All it really needs is an integer that uniquely identifies the current OS boot.
since time elapses between the read from the uptime counter and the read from the RTC.
Emacs allows for up to one second of slop in computing the boot time. (In other words, it assumes that reboots are at least one second apart.) So if there are minor errors in computing the boot time it should be OK. If the errors are greater than one second, though, lock-file may assume that locks are stale when they're not.
