macOS 13.1, chrony 3.2.
I modified check_current_time() in sched.c:
LOG(LOGS_WARN, "Forward time jump detected! %4ld sec”, raw->tv_sec - (prev_raw->tv_sec + elapsed_max.tv_sec) );
After the computer has been sleeping for some time (since about 10:10), I saw:
default 10:50:27.870498 +0700 chronyd Forward time jump detected! 2515 sec
default 11:03:37.562446 +0700 chronyd Forward time jump detected! 726 sec

default 13:15:12.492138 +0700 chronyd Forward time jump detected! 173 sec
Should I be worried about these erratic (and difficult to believe) jumps?
Should check_current_time() really run while the computer is (or should be) sleeping?
Gerriet.
