> *Problem description*:
> Batch request to do rolling restart does not work.
> The API says "201 created", but no requests are created.
> *Reason*:
> Server clock synced up with NTP daemon and was reset after Scheduler initialize and before
Scheduler start. 
> This caused the Thread.sleep() in the Scheduler.startDelayed() to be paused for a long
time since the native implementation relies on server clock.
