deferred evocation of an event against an object

Hi community

I was asked to try to evoke an event inside a deferred operation block. The idea is to “schedule” the execution of a particular task for the object Person in a very precise moment in the future. For example: in the custom field ccc_xxxx we need to save a date. When that date is reached, something must happen. Consider that I cannot deferred the date saving, as it must be there from the very beginning of the process.

Do you think this is possible?

Thank in advance.
