Kanjani Isikhathi Umhlaba

Thina zijwayele kwesikhathi, iqiniso lokuthi abantu emhlabeni emazweni ahlukahlukene futhi amadolobha niphila ngokuvumelana siqu iwashi zabo zendawo. Abenyukela lokhu ngokuhlukana, lapho isimo wafika isivumelwano ngalolu daba, futhi amanye amaqiniso athakazelisayo ezihlobene mkhuba embulungeni yonke, yini isikhathi ejwayelekile?

Indlela beveza isikhathi?

Cabangela Entweni enkulu kangako njengoba isikhathi ngokunembile wonke umqondo walo kweqiniso ngeke, kodwa yisho nje "Leli bhande" ingxenye yakhe. Olunye ulwazi jikelele: emhlabeni ezibhekwa njengezincwadi iwashi izinsuku okuyiwona Umhlaba lumayelana axis awo siqu. Lokhu ngakho - ibizwa ngokuthi usuku solar, ubude obuphakathi nendawo okuyinto kancane emahora langaphasi kulangu-24.

Isikhathi usuku akashintshi kuye kwendawo eklanywe njengomumo womhlaba. Ushintsho kuphela isikhathi samanje ezingxenyeni ezihlukahlukene zomhlaba. Nakuba ngaphambili abantu abazange cabanga ngaleli qiniso, ukuthuthukiswa kwezokuthutha izixhumanisi, ibhizinisi futhi ubudlelwane bezomnotho kuye kwaholela yokuthi umehluko ngokuhamba kwesikhathi baba ukuletha ezinye ngokuphazamiseka.

I Initiator of ukuvumelanisa nokwabiwa zesikhathi ezihlukile isibe Canadian Sandford Fleming. Yiqiniso, ukuthi Mnumzane Fleming wayengeyena abantu abavamile yezwe. Yena wayengumbulali unjiniyela abanamakhono, ogama ekudaleni ujantshi eCanada, umhambi wamazwe ngomdlandla. Kwakuphakathi nesikhathi ukudideka phakathi travel, bese traffic wesitimela, kuye kwaholela kulokho okuye kwabizwa kwethulwa isikhathi ejwayelekile. I yekucala isikhathi global uhlelo lwaqala ngo-1885 (ezinye imithombo - 1883) ngonyaka.

izimiso eziyisisekelo uhlelo

On siphi isimiso senziwa division zibe amazoni? Umqondo ilula ngokwanele: yilelo nalelo libe nesigaba egobhoza meridians, okuyinto ebekwe izinombolo kusukela 0 kuya 23. isikhathi ngasinye okwalandela noma odlule lihlukile zero iphuzu ihora elingu-1. Njengoba isiqalo, kwanqunywa ngesikhathi lo prime Meridian, okuyinto maqembu ngokusebenzisa British edolobheni ye-Greenwich. Njalo 15 ⁰ inohlelo Meridian entsha futhi ushintsho izoni yesikhathi. Ngakho, isikhathi ejwayelekile - lena uhlelo ezivamile , ekhiqizwa meridians 24.

amaqiniso ethakazelisayo

Njengoba kulindelekile, ukwethulwa kohlelo olunjalo emhlabeni wonke akuyona ngaphandle babhekwa yayo futhi amaqiniso athakazelisayo. Okokuqala thina akutshele ngalabo abathintekayo izoni yesikhathi eRussia

• System ehlongozwayo ngu Mnumzane Fleming, esimweni sethu yokutholwa ngo-1919 (kuphela unyaka emuva e-United States).
• Ngo-1930-ke laqanjwa "nokubeletha" (+1 ihora ezithile ejwayelekile), okuyinto yayikhona kuze 1981. okokufaka yakhe sasifanele ulondoloza amandla.
• Ingena izingxenye isikhathi kwaholela yokuthi isikhathi ezakhamuzini yasebhange ezahlukene ob e Novosibirsk kwahluka ku ihora. Umugqa kuhlukane siphela ngomfula, kodwa Nokho, namuhla, amawashi Novosibirsk ukukhombisa omunye futhi ngesikhathi esifanayo.
• Ngesikhathi kubusa amaSoviet ukulungiswa zezikhathi isikhathi zazenzeka cishe izikhathi ezingu-40 (yonyaka translation imicibisholo ebusika kanye nasehlobo - ungabali).

amaqiniso Global wesikhathi

• Usuku Line. It sidlula meridians 12. West kukaPythagoras offset usuku kusengaphambili mayelana wuhlangothi olusempumalanga. Isikhathi lapho emhlabeni wonke, kukhona omunye futhi ngosuku olufanayo (usuku) kuphela okwamanje lapho umugqa eshintsha usuku phakathi kobusuku, futhi phezu Meridian 0 - emini.
• Line ku eziQhingini zasePacific isikhathi umehluko namanye amaphuzu ezindawo ngema-awa lange-25.
• Umehluko isikhathi phakathi UTC futhi Nepal kuyinto amahora 5 nemizuzu engu-45.
• Ukweqa umngcele phakathi Afghanistan neChina wenze ukuhumusha imicibisholo amahora 3.5.
• I eyiNgisi bazokutshela ukuthi uma sibuyele sibheke phansi, ungabona ukuthi sekuyisikhathi manje e-India. Zonke sibonga yokuthi India wakhetha umehluko 5 ½ amahora mayelana "zero" isikhathi.

Lapha kuba, isikhathi ejwayelekile.
