MongoTimestamp is an internal type used by MongoDB for replication and sharding. It consists of a 4-byte timestamp (i.e. seconds since the epoch) and a 4-byte increment. This type is not intended for storing time or date values (e.g. a "createdAt" field on a document).
Nota: Unless you are writing an application that interacts with MongoDB's replication oplog or sharding internals: stop, go directly to MongoDate, do not pass go, and do not collect 200 dollars. This is not the class you are looking for.
