The DateTimeField Class

The DateTimeField class is the field definition for datetime values. It stores a python datetime object as a field. If time zone information is included in the datetime object, it will be included in the encoded data when this is encoded/decoded.

Timezones are only encoded as minute offset from UTC. When serialized in JSON, the encoding follows the Internet Engineering Task Force RFC 3339 spec. They are not actual timezones, for example Pacific Standard Time (PST), that you could use to derive expected daylight savings behavior.

DateTimeField is provided by the protorpc.message_types module.
