描述

I'm currently using this code to parse/dump timestamp, but I believe this should be in standard library. Should I create pull request, or have I missed another way to work with datetime/timestamp format?

class DateTime(ma.fields.DateTime):
    """
    Class extends marshmallow standart DateTime with "timestamp" format.
    """

    DATEFORMAT_SERIALIZATION_FUNCS = \
        ma.fields.DateTime.DATEFORMAT_SERIALIZATION_FUNCS.copy()
    DATEFORMAT_DESERIALIZATION_FUNCS = \
        ma.fields.DateTime.DATEFORMAT_DESERIALIZATION_FUNCS.copy()

    DATEFORMAT_SERIALIZATION_FUNCS['timestamp'] = lambda x: x.timestamp()
    DATEFORMAT_DESERIALIZATION_FUNCS['timestamp'] = datetime.fromtimestamp

研究方向
Look at the current implementation of the DateTime field in marshmallow, specifically the DATEFORMAT SERIALIZATION FUNCS and DATEFORMAT DESERIALIZATION FUNCS dictionaries. The issue proposes adding a 'timestamp' format that uses datetime.timestamp() for serialization and datetime.fromtimestamp for deserialization. Review the comments to see if there was any maintainer feedback or alternative approaches discussed. The change involves modifying the DateTime class to include the new format.
