Hello All , I have encounter an issue. we can get issue when we do step as follow:

1. change OS time , by slower then network time;
2. start our app, as sometime MM:SS start a job;
3. sync OS time, from network; -------------when time MM:SS get, bug job can't start-------------

From the docs:

Cron entries are stored in an array, sorted by their next activation time. Cron sleeps until the next job is due to be run. Upon waking:

• it runs each entry that is active on that second
• it calculates the next run times for the jobs that were run
• it re-sorts the array of entries by next activation time.
• it goes to sleep until the soonest job.

The important part is the last line. The Cron will go to sleep until the next job is due. So this isn't exactly a bug but wanted behavior. Maybe the package should consider some catching mechanic for system clock change events?
