How to retrieve the crontab line from an alteady scheduled job?

[fcrozetta]

I am using APSscheduler for a personal project and one thing i need to do is retrieve the scheduled jobs, and their information.

I am using the following command
apscheduler.schedulers.base.BaseScheduler.get_jobs(scheduler)
which returns a list of the jobs, like I need.

But in order to have this in a nice view in my frontend, i need to retrieve the crontab line from the trigger, but I am struggling to get it. Is there anything that would do "the opposite" of CronTrigger.from_crontab()? like a CronTrigger.to_crontab()

This would help a lot in many cases where the trigger needs to be exported to exported

I already saw it is not possible, and created the feature request #945
