@SmartiesTubesO America has 4 major time zones: Eastern (New York), Central (Chicago), Mountain (Denver), and Pacific (Los Angeles), plus Alaska, 1 hour earlier than Los Angeles, and Hawaii, 2 hours earlier than Los Angeles. The zones mostly change on State boundaries, so a State doesn't get split into 2 time zones. Presently, the U.S. is on Daylight Savings Time, so New York and EDT is now 5 hours behind Greenwich Mean time (GMT, or UT).
