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);

Yes, that is correct! The info on my previous post is wrong, sorry...
Please refer to the readme file, included in the TimeZone library
