Bug Description
Steps to reproduce:
1) Force a time delta
date -s "now - 1 hour"
2) Restart systemd-timesyncd to have it fix the time
systemctl restart systemd-timesyncd
Expected behavior:
The clock should be back in sync.
Actual (problematic) behavior:
The clock stays out of sync because the call to clock_adjtime() failed.
