An area in all parts of which the same TIME is kept. In general, each zone is 15° of LONGITUDE in width, with the GREENWICH MERIDIAN (0° LONGITUDE) designated as the central MERIDIAN of zone 0 and the remaining zones centered on a MERIDIAN whose LONGITUDE is exactly divis­ible by 15°. Zones are used in connec­tion with ZONE, STANDARD, and DAYLIGHT SAVING TIMES. Also calledtime zone.
