Since release 1.7.4, Avro Java will serialize and deserialize
instances of java.util.Date using the following schema:
This might thus be use as a standard Date schema, with other
implementations also treating this schema specially.
Or one can devise a different standard, common schema for datetimes,
perhaps something like:
Schema parsers might then be configured to pre-define this, so that
folks can simply refer to it with "type":"org.apache.avro.Datetime".
(For example, AVRO-1188 permits one to specify directories containing
schemas to include when Maven compiles schemas, protocols and IDL.)
For back-compatibility however, a schema parser must not be required
to include it. When a schema is printed, e.g., in a data file or in
an RPC handshake, the full schema will still be printed, so that
parsers that do not have this pre-defined can still process the data.
