tz-clock-layer

Pebble library for easily adding a clock with a secondary timezone (including automatic daylight savings) to your app.

Warning: Currently only supports a single instance.

Get your API key from Timezone DB.

You can find a list of timezones here: Timezone list.

Usage

pebble package install ...

// This is a simple example, demonstrating the basic usage.
#include <tz-clock-layer/tz-clock-layer.h>

static TzClockLayer *s_remote_time_layer;

static void tick_handler(struct tm *tick_time, TimeUnits units_changed) {
  tz_clock_tick_event(s_remote_time_layer, tick_time, units_changed);
}

static void window_load(Window *window) {
  Layer *window_layer = window_get_root_layer(window);
  GRect bounds = layer_get_bounds(window_layer);

  s_remote_time_layer = tz_clock_layer_create(GRect(0, 68, bounds.size.w, 34), "YOUR-API-KEY", "America/Los_Angeles");
  layer_add_child(window_layer, s_remote_time_layer);

  tick_timer_service_subscribe(MINUTE_UNIT, tick_handler);
}

static void window_unload(Window *window) {
  tz_clock_layer_destroy(s_remote_time_layer);
}

// Add to your app.js
var TzClock = require('tz-clock-layer');
var tzClock = new TzClock();

Pebble.addEventListener('ready', function(e) {
  Pebble.sendAppMessage({'APP_READY': true});
});

Pebble.addEventListener('appmessage', function(e) {
  tzClock.appMessageHandler(e);
});
