This is probably about adjtimex / host_adjust_time. > And strictly speaking, `time` can be modified using `host_set_time64` > [1], maybe we can have a comment better than 'time since bootup'. Yes, it's not the delay since bootup, but the time as gotten from bootup (see inittodr), and then possibly updated by host_set_time. So it's rather the (unadjusted) wallclock time. Samuel
