These values vary depending on containerization, existence of a Real Time Clock, etc. - UnitsLoadStartTimestamp property on /org/freedesktop/systemd1 The start time of the service manager, according to systemd itself. Seems to be more reliable than UserspaceTimestamp when the RTC is in local time. Works unless the system was not booted with systemd, such as in (most) containers. - st_mtime of /proc/1 Reflects the time the first process was run after booting. This works for all known cases except machines without a RTC---they awake at the start of the epoch. - btime field of /proc/stat Reflects the time when the kernel started. Works for machines without RTC iff the current time is reasonably correct. Does not work on containers which share their kernel with the host---there, the host kernel uptime is returned.
