Delaying the Step Execution of a Plugin

Hi,

I have a Plugin which triggers on an update of a field. The field gets updated around midnight by the SYSTEM and a lot of records get updated around the same time. This causes my plugin to act strangely and I would prefer if I could Delay the execution of my plugin to around 5 mins after the field has been updated as my plugin works 100% when I update the field manually.

Is this even possible?
