/*
 * TimeAlarmExample.ino
 *
 * This example calls alarm functions at 8:30 am and at 5:45 pm (17:45)
 * and simulates turning lights on at night and off in the morning
 * A weekly timer is set for Saturdays at 8:30:30
 *
 * A timer is called every 15 seconds
 * Another timer is called once only after 10 seconds
 *
 * At startup the time is set using sntp via configTime
