Struktur zona waktu negara ini

The US mainland — five continental timezones + DST

Daratan AS mencakup empat zona waktu (Timur, Tengah, Pegunungan, Pasifik), dengan Alaska menambahkan zona waktu kelima dan Hawaii ke zona waktu keenam. DST hampir bersifat universal — diamati dari pertengahan Maret hingga awal November — kecuali di Arizona (tanpa DST) dan Hawaii (tanpa DST). Perusahaan multi-kantor di AS menggunakan Waktu Bagian Timur untuk kalender bersama, terlepas dari kantor pusatnya, jadi "10 AM ET / 9 AM CT / 8 AM MT / 7 AM PT" adalah notasi empat arah standar pada undangan rapat internal.

DST is nearly universal (except Arizona, Hawaii, most of Saskatchewan) and runs March → November. Business scheduling defaults to Eastern for multi-office US corporations regardless of headquarters.
