So is this correct? The "2" meaning change the time at 0200?
Code:
// --------------------------------------------------------------------------------------
// Define rules for Auto Summer Time Display, and clock adjustment
// --------------------------------------------------------------------------------------
// Example for Australia Eastern Time Zone (Sydney, Melbourne)
// TimeChangeRule aEDT = {"AEDT", First, Sun, Oct, 2, 660}; //UTC + 11 hours
// TimeChangeRule aEST = {"AEST", First, Sun, Apr, 3, 600}; //UTC + 10 hours
// Timezone myTZ(aEDT, aEST);
TimeChangeRule usEDT = {"USEDT", Second, Sun, Mar, 2, -240}; //UTC - 4hours
TimeChangeRule usEST = {"USEST", First, Sun, Nov, 2, -300}; //UTC - 5hours
Timezone myTZ(usEDT, usEST);
