Esihlelwe Isikhathi Somhlaba: kungani nokuthi laqanjwa?

isikhathi Proper kubaluleke kakhulu kuleli zwe lanamuhla, lapho isigqi wokuphila liye landa kakhulu. Kodwa ubunzima kuba phambi zesikhathi ezihlukile - eqinisweni lapho sisebenzelana abantu abavela kwezinye izindawo zomhlaba kubalulekile ukuba ngandlela-thile lokuma ezivamile. Ukuze wenze lokhu, futhi kufanele esihlelwe isikhathi jikelele. Kodwa ingabe abantu balithola kanjani njalo kwesimiso esinjalo?

Yini esihlelwe Isikhathi Somhlaba (UTC)?

Kuleli zwe lanamuhla aphakeme yizinhlobonhlobo zenani - lwemali olulodwa, ulimi, njll Kodwa izoni yesikhathi esisodwa, faka akunakwenzeka, ngoba lapho umuntu Nenkabazwe kosuku, kwesinye - .. Umelusi. Ngaphezu kwalokho, kukhona okuthiwa bendawo isikhathi solar, uyeza kuhambisana indlela izibani ukuhambisa esibhakabhakeni kusukela empumalanga kuya entshonalanga. Kodwa isikhathi esishintshashintshayo kumele ibe bahlobene ngandlela-thile, zithinta abathile iphuzu. Ukuze wenze lokhu, futhi kukhona UTC - esihlelwe Isikhathi Somhlaba. It wavela kuye dudula isimo, bemisa insimu yalo iwashi. Kodwa kwenzeka kanjani ukuba njalo kwesimiso esinjalo?

Umlando ukwethulwa ejwayelekile olulodwa

Ekuqaleni esintwini inquma isikhathi lapho ilanga lingakhona. Okwamanje Wadlulela waso eliphakeme, kwenza kwaba nomfutho omkhulu ntambama. Kuyinto kule alelo washi lika isimiso nokusebenza. Kodwa le ndlela akuyona olunembile kakhulu, ngaphezu, ekukhuleni komphakathi zidinga yizinhlobonhlobo okukhulu. Ngokuhamba kwesikhathi, njengoba ezweni elisha, futhi abantu bayaqaphela ukuthi udinga ukufaka amazoni niwabophe ndawonye endaweni yokuqala ngezinhloso Ukuqondiswa kwemikhumbi, yasungulwa GSM uhlelo (sase-Greenwich Mean), ngakho okuthiwa ngenxa yokuthi umugqa owehla nembulunga okuyi avuleka, ngawo ibala isikhathi badabula Observatory saseGreenwich.

By the way, ngaphambi ukwethulwa lokhu okujwayelekile emazweni ahlukahlukene zisebenzisa amaphuzu abo zero. Njengoba umthetho, meridians isilinganiso kulokhu badabula Observatory endawo e-France - Paris, Russia - .. I Pulkovo, njll Kodwa ukuntuleka indinganiso owodwa ungakhululekile. Futhi ngo-1884 i-Greenwich Meridian Zero kwavunyelwana. Ngokusho kwakhe, hhayi kuphela ukuvumelanisa amawashi, kodwa futhi ukucacisa izixhumanisi ezindawo - longitude.

Manje lokhu kubizwa ngokuthi standard UTC, noma esihlelwe Isikhathi Somhlaba. Ngokungafani GMT I, it is kuqhathaniswa ne iwashi le-athomu, futhi njalo eminyakeni 2-3 ukuchibiyela esikalini ngesimo "okungalé" yesibili. Lokhu kwenziwa ukuze alethe isikhathi sakho yezinkanyezi.

Ukumaka amazoni

Isikhathi ngesikhathi Greenwich Meridian ubalwa. Ukuze kube lula, libizwa ngokuthi umehluko naye, okungukuthi UTC +1, UTC-8, nokunye. D. It is hhayi njalo wasebenzisa meridians, njengoba kwezinye izimo kuyoba kancane ukuba kuhlalwe esiwuphawu wonke sezigaba zezikhathi. Lokhu ngenhlanhla kwaba isizathu ezinye izici ezithakazelisayo kakhulu isikhathi emazweni ahlukene. Kodwa lokhu, kuzoxoxwa ngakho kamuva.

ukusetshenziswa

Ngakho lapho sekumcacela ukuthi zihlelwe ezinjalo, kuyafaneleka ukuxoxa indlela lelisetjentiswa ezweni lanamuhla. Okokuqala, i-zero Meridian sisabenza navigation - kokubili phansi olwandle emoyeni. Okwesibili, ukuhwebelana kwembulunga yonke washiya isigxivizo yayo phezu isidingo isikhathi ezivamile inkomba. Izingcingo zenkomfa phakathi kwabantu elise izingxenye ezahlukene zomhlaba, aqokwe UTC.

By the way, kwezinye izindawo, amazoni musa empeleni zikhona. Sikhuluma-Arctic Antarctic, lapho isikhathi uye kunemibandela eyamukelwayo UTC + 0. Eqinisweni, abacwaningi eziteshini polar kukhona ukubala amahora njengoba ukhululekile. Kuyefana nasendleleni le osomkhathi abasebenza emzileni eMhlabeni.

amaqiniso ezithakazelisayo

System kuhlanganise Coordinated Isikhathi Somhlaba, kwamiswa isikhathi eside, futhi umphumela waba ukuthi kwakukhona ezinye izici nelukuluku.

• Akukho olusemthethweni isifinyezo UTC ukuqaqwa. Ngo-1970, lapho le ndinganiso lwaqala, kuxoxwa ongakhetha TUC (Temps Universel Coordonné) kanye AGENDA (esihlelwe Isikhathi Somhlaba). Ngenxa yalokho, kwanqunywa ukuba ayeke eseneminyaka UTC hlangothi.
• Novosibirsk yasungulwa on amabili lomfula, okuyisona ncamashi ku ihora Meridian. Futhi isikhathi eside emzini kukhona khona ababili sikhathi. Ngaphambi kokwakhiwa ngo-1955 kwaleli bhuloho lokuqala awusebenzi ibakhathaze ethile, ngoba izingxenye ezimbili laseNovosibirsk neze zihlotshaniswa nomunye. Kodwa ngo-1958, leli dolobha weza isikhathi esisodwa.
• Ngokunengqondo, Umehluko omkhulu ngesikhathi phakathi kwezindawo ezimbili zomhlaba kufanele kube amahora angu-24. Kodwa eqinisweni kukhona 26 wonke sezigaba zezikhathi. Esikhathini Pacific, kuqhathaniswa eduze komunye nomunye kukhona ezimbili esiqhingini States: American Samoa Archipelago Line. Isikhathi umehluko phakathi kwayo kube ngamahora angama-25. Kwenzeka ngenxa Line Islands, ngaphambili okungewakho UK, kulinganiswa ngesikhathi kusuka Australian, yaphenduka UTC + 14. A Samoa UTC-11 izenzo ngokuhambisana umehluko kusuka Melika ezwekazini.
• Kwezinye izingxenye Australia ngezinye izikhathi avele ovundlile wonke sezigaba zezikhathi. Lokhu kungenxa yokuthi akubona bonke uthi lihamba esikhathini ebusika.
• Hhayi ngaso sonke isikhathi ncamashi umehluko nge-Greenwich namahora. ENepal izenzo UTC + 5: 45, kwamanye amadolobha Australian 8: 45, futhi leli qoqo leziqhingi laqala we Chatham, New Zealand + 12: 45.
