Time.zone() and Time.local()

Hi Everyone, My photon is not printing the correct time here in Australia. We are in the Greenwich Mean Time + 10 zone. I tried the following in my Setup() function: Time.zone(10); Time.zone(-10); Time.zone(+10); Time.zone(0); None of these worked. Here are the important parts of my code: void setup() { Time.zone(10); } void loop() { ... currLocTime=Time.local(); Serial.println(Time.format(currLocTime, TIME_FORMAT_ISO8601_FULL)); ... } It outputs something like this: 2016-0…

Time.now() and Time.local() only return a numer of seconds without any further information about when the counting started.
And Time.timeStr() just takes a number of seconds (without caring about the way how you got that number) and formats that according to the data stored in the Time object (especially the zone).

A over-simplified example:

int zone = -5;
int now() { return millis()/1000; }
int local() { return now() + zone*3600; }
String timeStr(int sec) {  return ("The localized time is " + String(sec + zone*3600) + " seconds after bootup"); } 

If you call that the way you did above, you'll see similar behaviour (local() will show twice the zone offset).
And when you set zone = 0, you'll get the same result for local() and now()
