The timestamp property in AMQP 0-9-1 is defined as a 64bit Unix
timestamp, which is seconds since 1970/1/1, instead of a string. Also
note the comments in the AmqpTimestamp class.

As you say, if consumers and producers both agree on a string date
format and you don't care about interoperability then you can include a
data string as a header instead of the property.
