Proposed change

Something like this would be sooooo helpful:

ns = await nats.connect("localhost:4222")

await ns.cron.set("my_periodic_task_id", "*/1 * * * *", "my_topic",  "my message".encode())

await ns.cron.set("my_one-shot_task_id", "2025-04-20T18:40:00+02:00", "my_topic",  "my message".encode())

task = await ns.cron.get("my_one-shot_task_id")

await ns.cron.del("my_periodic_task_id")

When these tasks are one shot they should be automatically be removed after triggering and sending their message to the target topic.

Use case

In case we are dealing with timed events that need to be processed. For example when we are dealing with calendar (ical) events or having to send out emails etc...

Contribution

I'm not familiar with the NATS code base but would be happy to contribute with support.
