I have not be able to get this to work , no time messages received .
No problem with other python rest and mqtt examples.
No problem with adafruitio_17_time.py REST example.

Can you post the output from your terminal when running this example?

The output observed is from the code print statements indicating client.scribe action :
* Subscribing to /time/seconds
* Subscribing to /time/millis
* Subscribing to iso-8601
...
repeats forever

Can you post your code (even if it's our example)

ok ... see below:

# Import standard python modules.

Thank you for the output log - I noticed a bug within mqtt_client and the time example and fixed both of them this morning (https://github.com/adafruit/Adafruit_IO_Python/pull/95)

Please reinstall (or upgrade) the library to v2.3.1 (https://github.com/adafruit/Adafruit_IO ... /tag/2.3.1) and run the new example code (https://github.com/adafruit/Adafruit_IO ... tt_time.py).

[mikec]

yes thank .. working now...
