You will need to store them somewhere extra.

Or you can create your custom map implementation which would either extend Java's hashmap or use an hashmap internally and would additionally remember the last date of any action performed on your dataset, you seek to remember.

This would have the advantage that it would be ubiquitous and you wouldn't need to care about it within your algorithm, which uses the hashmap
