Setting property absolute_expiry_time caused send to fails

[tonygleck]

• UAMQP Package Version: uamqp-1.2.6
• Operating System: Linux Ubuntu 18.04
• Python Version: 3.7

Describe the bug
When I set the absolute_expiry_time on a message property I get a failure, if I remove the setting of absolute time and set a different property it works correctly.

To Reproduce
Steps to reproduce the behavior:
Run the following script:

import uamqp
import time
from uuid import uuid4

device_id = "<device_id>"

target = "<target here>"
amqp_client = uamqp.SendClient(target)

msg_content = "Test Message"
msg_props = uamqp.message.MessageProperties()
msg_props.message_id = str(uuid4())
msg_props.to = "/devices/{}/messages/devicebound".format(device_id)

send_message = "Sending c2d message 4"
msg_props.absolute_expiry_time = int(time.time() + 3600)

print("Sending Message")

message = uamqp.Message(
    msg_content, properties=msg_props
)
amqp_client.queue_message(message)
results = amqp_client.send_all_messages(close_on_done=True)
if uamqp.constants.MessageState.SendFailed in results:
    print("C2D message send failure")

Let me know if I'm missing something here.

hey @tonygleck , apologize for the delayed response.

thanks for you detailed instruction to reproduce, may I ask:

1. are you sending message to Azure IoTHub?
2. would you be able to turn on networking tracking and enable logging to see if there's any error happening during the sending process? that would be:

import logging
logging.basicConfig(level=logging.INFO)

amqp_client = uamqp.SendClient(target, debug=True)

it would be helpful and convenient for us to debug if you could paste the log here :)
