Ironium v0.11.0 Release Notes
➕ ADDED queue.delay works just like queue.push but delays processing of the job.
queue.delay(job, duration, callback?)
0️⃣ Duration is either a number or a string. The default unit is milliseconds, but you can specify a string with units, such as "5m" or "3 hours".
Valid units are
years. You can write each unit as plural ("1 hours"), singular ("1 hour") or first letter only ("1h").
