The documentation for Boottime concludes with "(since Linux 4.17; identical to 'Monotonic')", which sounds as if this behaves the same as Monotonic on a modern linux system. That is not the case, both experimentally and based on reading the clock_gettime(2) man page on my linux system here, which states:
CLOCK_BOOTTIME (since Linux 2.6.39; Linux-specific)
A nonsettable system-wide clock that is identical to
CLOCK_MONOTONIC, except that it also includes any
time that the system is suspended. This allows ap‐
plications to get a suspend-aware monotonic clock
without having to deal with the complications of
CLOCK_REALTIME, which may have discontinuities if the
time is changed using settimeofday(2) or similar.
I suspect that the parenthetical got into the documentation accidentially and it should just be removed.
