question

@volkhin, do you still see this issue if you reboot the Echo device by unplugging / plugging back in? If so, can you confirm that (1) this is still happening well after the gadget has connected, (2) what type of Echo Device you are working with, and (3) if possible, the Echo Device firmware version you are working with. For #3, go to Device Settings-->About-->Device Software Version in the Alexa App. If you are working on a screen-based device, go to Settings-->Device Options-->Software Version

Speaking with the Alexa Gadgets team said that it is possible to get multiple "timeinfo" directives containing the same value if they are sent fractions of milliseconds apart within the same second.

One plausible scenario that came to their mind was that Echo devices may send multiple "timeinfo" directives, when multiple Echo devices are connected to ensure all gadgets get the time information.

Next, to the question of recommended actions they suggested that gadgets can de-dupe the "timeinfo" value by keeping track of the most recent value received and comparing it to the incoming value to evaluate whether the incoming value is the same as the old (to the granularity of seconds) or whether the value has increased.
