CreationTimeUtc is not handled in message

[reddyduggempudi]

Device can buffer up messages and send them all at some frequency. To accomplish, you can set CreationTimeUtc (payload creation time) in the event message. common.Message has this field, but looks like it is not set in the transport.send() https://github.com/amenzhinsky/iothub/blob/master/iotdevice/transport/mqtt/mqtt.go#L480
You need to set "$.ctime". Similarly other properties need to be honored like https://github.com/Azure/azure-iot-sdk-csharp/blob/master/iothub/device/src/Transport/Mqtt/MqttIotHubAdapter.cs#L1197

But I'm not sure about time format though, Azure uses different time formats across API, for now it simply pushes ctime to amqp.ApplicationProperties that goes to msg.Properties["iothub-creation-time-utc"] as a raw string with no time parsing.

I followed up internally with the team. The format for this time should be Format("2006-01-02T15:04:05")
E.g.: 2021-23-03T17:38:59

So, please change it to above format.
