"समय क्षेत्र" का संशोधनहरू बिचको अन्तर

'''समय क्षेत्र''' संसारको त्यस्तो क्षेत्र हो जहाँ एउटै [[समय]] अपनाइएको हुन्छ । यसलाई '''स्थानीय समय''' पनि भन्ने गरिन्छ । धेरैजसो एक आपसमा जोडिएका समय क्षेत्रहरूमा एक घण्टाको फरक हुन्छ र सामान्यतया [[ग्रेनिच]] समयका आधारमा निर्धारण गरिन्छ । (see also [[Coordinated Universal Time|UTC]]).

 

 

Standard time zones can be defined by geometrically subdividing the Earth's [[spheroid]] into 24 [[lune]]s (wedge-shaped sections), bordered by [[meridians]] each 15° of [[longitude]] apart. The local time in neighbouring zones would differ by one hour. However, political र geographical practicalities can result in irregularly-shaped zones that follow political boundaries or that change their time seasonally (as with [[daylight saving time]]), as well as being subject to occasional redefinition as political conditions change.
