Receiving only UTC time from Home Assistant controller

[proddy]

I'm not sure if this is a MySensors or Home Assistant issue, but using the example at https://www.mysensors.org/build/display to read the time from my HA controller, it always pulls the UTC time where in the MySensors library documentation here it states that void receiveTime(unsigned long ts); returns ts "Adjusted for timezone by controller."

I have the time_zone parameter correctly configured in my Home Assistant's configuration.yaml file.

As a workaround I have the sensor node convert the time using this piece of code:

#include <Timezone.h>
#include <TimeLib.h>
TimeChangeRule CEST = { "CEST", Last, Sun, Mar, 12, 120 }; // Central European Summer Time, 2 hrs offset
TimeChangeRule CET = { "CET ", Last, Sun, Nov, 5, 60 };   // Central European Standard Time, 1 hr offset
Timezone CE(CEST, CET);
: 
:     
TimeChangeRule * tcr;
time_t t = CE.toLocal(controllerTime, &tcr);
RTC.set(t);

But it would good to know if its a bug or I'm just doing something incorrect?

Hi!

This is a bug or at least a deviation from the mysensors API. We should fix it. Should be just a matter of using the correct time function, I think.

@martinhjelmare is this something I can help contribute too?

Yes! Make a PR to pymysensors repository at github. I think calendar.timegm(time.localtime()) should return the correct time.

@martinhjelmare I made a PR. https://github.com/theolind/pymysensors/pull/80
