Ruby on Rails + Sidekiq: How do I change a scheduled job start time?

I dont think editing/updating jobs is the way. I usually create new job each time something changes. And then in the job itself check if the time to execute certain task is right... If the time is right, continue with the task otherwise just skip...

This is probably not answering the question, but this question is first on google for "sidekiq increase the time of an already scheduled job".

Sidekiq has this method(reschedule) on a SortedEntry job.

Find the job:

job = Sidekiq::ScheduledSet.new.find_job(job_id)

reschedule the job:

job.reschedule(Time.now + 2.hours)
