How to create a plugin that works at a specific time in jira?

Acroo

Important: I use atlassian-sdk. (java)

For example: I need to create a plugin that clears the field in the issue every day at 5 am.

Any ideas?

You can write a "service" to run regularly, searches for issues where the field is set and clear it out.
