I not sure is it is a bug but when I have tried save() a entity with a datetime property appear this error.
pb_attr, pb_value = helpers.get_protobuf_attribute_and_value(value)
File "/usr/local/lib/python2.7/dist-packages/gcloud/datastore/helpers.py", line 39, in get_protobuf_attribute_and_value
name, value = 'timestamp_microseconds', time.mktime(val.timetuple())
NameError: global name 'time' is not defined
