How to check when a job will be run next?

[sheharyarn]

Pretty much as it says on the can. For example, given a config like this:

config :my_app, MyApp.Cron.Scheduler,
  jobs: [
    {"@hourly", {MyApp.Cron.JobA, :run, []}},
    {"@daily", {MyApp.Cron.JobB, :do_something, []}},
  ]

How can I check when each of the jobs will be run next? Getting the next run datetime for a named job will also be helpful.

For this you can use crontab directly: https://hexdocs.pm/crontab/Crontab.Scheduler.html#get_next_run_date/3

Ah, I see. I came across the crontab package earlier but didn't realize that's what quantum uses underneath. This is exactly what I needed.

Thanks!
