This attribute must only be applied to properties of DateTime, DateTimeOffset, Timestamp,
or the nullable equivalents, or a protobuf Timestamp.
This attribute is ignored when serializing a document to Firestore.
This attribute must not be applied on a property which also has FirestorePropertyAttribute.
When deserializing a snapshot representing a missing document, nullable properties will be set to a null value; non-nullable
properties will be set to the default value of the type (0001-01-01 for DateTime and DateTimeOffset, 1970-01-01 for Timestamp).
