Gearman and quest delay?

Question

Gearman

I discovered Gearman, yes, yes, I'm a slowpoke)
Great joke, but I can't figure out if it's possible to specify the following conditions:
- transfer the job to the worker at a certain time (for example, 08/12/2018 13:15)?
- if the worker reported a runtime error, then repeat this job after x-minutes, n-number of times
Well, or advise MQ with such capabilities)
Thank you)

Celery
German is simple, and it seems that apart from two priorities, nothing else stands out
