Sebenzisa i-HTTP Date ne-Age ekuhloleni isikhathi okungalungile nge-proxy

Sebenzisa impendulo ye-HTTP Date ekuhloleni isikhathi okungalungile futhi ucabangele iminyaka yempendulo egciniwe ngaphambi kokuyihumusha.

Impendulo yewebhu inganikeza inkomba yesikhathi engaqondile uma indlela yokuphuma etholakalayo iyi-proxy ye-HTTP. Ngomkhawulo olawulwayo othembayo iwashi lawo, cela izihloko zempendulo yawo ngale ndlela:

curl --head --proxy http://proxy.example.net:8080 https://time.example.net/

Umkhami uyisibonelo somkhawulo, hhayi insiza yesikhathi yomphakathi. Uma umkhawulo othembekile ufinyeleleka emphakathini futhi inethiwekhi ivumela umlamuli womphakathi ongadingi ukuqinisekiswa, uhlu lwama-proxy e-HTTP lungahlinzeka ngabagqatswa bekheli le-proxy; alinikezi iwashi elithembekile. Impendulo ingaqukatha:

Date: Thu, 29 Oct 2026 08:15:20 GMT
Age: 45

Date imele isikhathi lapho umyalezo we-HTTP waqala khona. Lokho akusho ngempela "isikhathi samanje kule klayenti". Impendulo egciniwe ingaba ne-Date endala kuyilapho isasebenza ekusetshenzisweni kabusha. Inkambu ye-Age iveza isilinganiso segcino mayelana nobudala bempendulo ngemizuzwana.

Kule mpendulo eyisibonelo, ukwengeza iminyaka ebikiwe kunikeza inkomba engaqondile cishe ku-08:16:05 GMT ngaphambi kokucatshangelwa ukubambezeleka kokudlulisa kanye nephutha lesilinganiso. Lokho akulona ukuphambuka okulinganisiwe. Rekhoda ukuthi iklayenti lathumela nini isicelo futhi lathola nini impendulo uma uhlelo lufuna ukuchaza ukungaqiniseki.

Amanye amaseva awakusekeli ukusebenza kwe-HEAD njengoba kulindelekile noma ashiya imethadatha yesikhathi esebenzisekayo. Thatha inkambu engekho noma engakhiwe kahle njengokuhlola kwesikhathi okuhlulekile. Impendulo ye-407 ichaza ukushintshana kwe-proxy, ngakho i-Date yayo akuyona ngokuzenzakalela iwashi lomkhawulo obufuna ukuwubuza.

Khetha ukuthi ukuhlola kungenxa yani

Lokhu kungasiza ekuboneni iwashi elingalungile ngamahora noma ngezinsuku, noma ekufakeni isigxivizo sesikhathi esiseduze esilinganisiwe embikweni wokuxilonga. Akunikezi ukukhethwa kwewashi nokucutshungulwa kokubambezeleka/ukuphambuka kwe-NTP, futhi akufanele kuqondise ukulungiswa kwewashi okuzwela ukunemba.

Ukuze kuvumelaniswe uhlelo lwangempela, sebenzisa insiza yesikhathi evunyelwe yinethiwekhi kanye nendlela yokuvumelanisa isikhathi esekelwayo. Indlela ye-proxy ye-HTTP ingathwala ukuhlolwa kwezihloko okungenhla ngaphandle kokwenza iphrothokholo ye-NTP ngokwayo itholakale.
