Add Timestamp data type like Datetime

When I use firebase firestore some problems, I face is firestore accepts DateTime but hive does not accept timestamp datatype on putting data into the hive database pls add some features to manage firestore and hive database as an easy way to implement.

The issue mentions Firestore and Hive but names no files, tests, or entry points. First clarify the intended Timestamp representation and the Firestore-to-Hive workflow; completion should be defined by a reproducible example and tests showing that timestamp data can be stored and retrieved correctly.
