We will be deploying a new feature to our MQTT broker tomorrow morning. We will start broadcasting
the current time in two formats at
time/seconds at one second intervals. This should
allow users to easily keep track of the current time from devices without real time clocks.
Here are a couple examples of the payloads:
topic: time/ISO-8601 payload: 2016-06-01T21:34:12.629Z
Seconds since Unix epoch:
topic: time/seconds payload: 1464816851
