Ulitshintsha njani ixesha kwiLinux

Kule post siza kubona indlela yokutshintsha ixesha kwiLinux. Asikuko ukuba kunzima kakhulu kuba uninzi lwe desktops lubandakanya iiwizards ezikuvumela ukuba uzenze ngokucofa kabini, kodwa sisizathu esihle sokufunda ngakumbi malunga nendlela esebenza ngayo ikhompyuter yethu kunye nenkqubo yokusebenza.

Ngemihla yakudala iwotshi yayiyinto enqabileyo, into eyayiphiwa njengesipho xa uneminyaka engama-25 usemsebenzini okanye udluliselwe njengelifa kunyana omkhulu. Enyanisweni, kwakuyinto yokuqala utata kunye nabazalwana bakhe baseGalician abavela kwamanye amazwe bathenga njengotyalo-mali xa beqala ukufumana imali e-Argentina.

Nangona kunjalo, ngokufika kwamaJapan, iindleko zokuvelisa ziye zancinci kwaye kungekudala ezinye izixhobo ezinje ngemicrowaves, VCRs kunye nabenzi bekofu babandakanya lo msebenzi. Xa izixhobo eziphathwayo zisiba zikhulu ngakumbi kwaye ziphathwa, iwotshi yesihlahla yakudala yayiphulukana nokubalasela. Namhlanje iphila ngendlela yee-smartwatches, kodwa ekusebenzeni ziyi-accessory kwifowuni.

Andazi ukuba kutheni iinkqubo zokusebenza zibonisa iwotshi. Ndicinga ukuba ngenxa yokuba indawo engenanto kwibar ibonakala imbi kwaye, ekubeni idinga iwashi ekusebenzeni kwayo, ukubonisa ixesha kwakungeyona into enzima kakhulu.

Ulitshintsha njani ixesha kwiLinux

Ukuba uneWindows kunye neLinux efakwe kwikhompyuter yakho, uya kuba uqaphele ukuba, ukuba uphuma kwiLinux kwaye ungenise iWindows, inexesha elahlukileyo kunelo lasekhaya. Oku kungenxa yokuba i-Linux ithatha ukuba iwotshi ye-hardware ikwi-sync kunye ne-Coordinated Universal Time, ngelixa i-Windows ithatha ukuba ikwixesha lasekhaya. Inkqubo yokusebenza yamva nje izakusetyenziswa ihlengahlengisa iwotshi yehardware ngokweemfuno zayo.

Isisombululo kukwenza ukuba iWindows yenze izibalo zayo ngokusekelwe kwixesha le-UTC okanye i-Linux iyenze ngexesha lendawo. Kulula kakhulu ukwenza utshintsho lweLinux ukusukela oko kufuneka sibhale umyalelo:
sudo timedatectl set-local-rtc 1

Ngokubanzi, ukuhanjiswa kweLinux kukubuza ukuba yeyiphi indawo yexesha oza kuyisebenzisa kwaye ukusukela ngoko ukuya phambili baya kulungelelanisa ixesha ngokuzenzekelayo.nokuba uthatha ulwazi kwiseva yexesha lomsebenzi womnatha okanye wenze izibalo ezihambelanayo ukusuka kwixesha eliboniswe ngumncedisi wexesha jikelele. Kwimeko apho uxhulumaniso kumncedisi wexesha lomnatha alufumaneki, abaphuhlisi bahlala bequka iifayile ezinemiyalelo ukuze inkqubo ikwazi ukubala ukuhluka phakathi kwexesha lasehlotyeni nasebusika.

Iidesktop ezahlukeneyo zikuvumela ukuba ubhale ngaphezulu ungqamaniso oluzenzekelayo kwaye ulusete ngesandla.

Ukusuka kwi-terminal sinokuhlengahlengisa ixesha ngomyalelo:
sudo timedatectl set-time hh:mm:ss
Umzekelo, ukuseta ixesha ngekota ukuya kweyesithathu emva kwemini senza:
sudo timedatectl set-time 14:45:00
Ukurhoxisa ungqamaniso oluzenzekelayo lwexesha kunye neseva yenethiwekhi sisebenzisa lo myalelo:
sudo timedatectl set-ntp false
Ukuyivula kwakhona sibhala umyalelo:
sudo timedatectl set-ntp true
Singazibona iindawo zexesha ezikhoyo nge:
timedatectl list-timezones
Kwaye utshintshe ukusuka kwenye uye kwenye nge:
timedatectl set-timezone CONTINENTE/PAÍS
o
timedatectl set-timezone Continente/País/Ciudad
Kwaye kwezinye iimeko
timedatectl set-timezone Continente/Ciudad/Localidad.
Kuyo nayiphi na imeko, coma njengoko kubonakala kuluhlu.
Umzekelo:
timedatectl set-timezone America/Indiana/Indianapolis

Ukuba awufuni ukutshintsha indawo yexesha unokubona ukuba leliphi ixesha kwenye ngomyalelo:

TZ=Zona_horaria date Ukutshintsha indawo yexesha kunye negama elivela kulo kuluhlu. Umzekelo:
TZ=America/Indiana/Indianapolis date
Ukubona ixesha kwiwotshi yehardware, sebenzisa lo myalelo:
hwclock -r
Sinokungqamanisa iwotshi yehardware kunye newotshi yenkqubo ngokuchwetheza:
hwclock --systohc

Ezinye izicelo ukubona ixesha

Ukuba awuyithandi iwotshi eza nedesktop yakho, koovimba sinezicelo ezininzi esivumela ukuba sibone ixesha. Ezinye zazo zezi:

Amaxesha

Isenokuvela kubaphathi bempahla phantsi kwegama Iiwotshi. Iyinxalenye yesicelo seprojekthi ye-GNOME kwaye ibandakanya iinkqubo ezininzi ezinxulumene nokulinganisa ixesha kubandakanya:

• Iiwotshi zokubonisa ixesha kwiindawo ezahlukeneyo zehlabathi.
• Iialamu
• Izixhobo zokubala ngasemva.
• Ukumisa

Iwotshi ye-analog

Ifumaneka kumbindi wesoftware yonikezelo olusekwe kwi KDE desktop, Le wotshi ye-analog yongezwa kwi-desktop kwaye ibonisa ukudlula kweeyure ngokuma kwezandla.

DClock

Esinye isihloko esikhoyo kwiindawo zokugcina. Njengoko kubonisiwe ngu-D kwisihloko sYiwotshi yedijithali ezenza ngathi ibonisa amanani ngee-leds. Ukongeza, ibonisa umhla kwaye ikuvumela ukuba usete i-alamu.

ixesha lokunqunqa

Le nkqubo yokugcina ibonisa ixesha kwiindawo ezahlukeneyo zehlabathi. ukuze sikwazi ukuyibona kufuneka sibeke ikhesa kwaye sicofe kabini kwisixeko esifuna ukuyibona ishedyuli yayo.

esibomvu

Isimbo sewotshi yedijithali endala inkangeleko yayo inokuguqulwa kusetyenziswa amaphepha esitayile. Ifumaneka ngefomathi Flatpak.

isibali-xesha somhla

Desde Ivenkile ekhawulezayo sifumana olu setyenziso luluncedo olubala imihla. Ifumana iziphumo ngokusekelwe kwixesha lokuqala/lesiphelo kunye noluhlu lwexesha okanye uluhlu lwexesha ukusuka kwixesha lokuqala nelokuphela nomhla

Iikhompyuter zilinganisa njani ixesha

Mhlawumbi eyona ndlela indala yokulinganisa ixesha yindawo elimi ngayo ilanga. Imini yayilithuba elidlulayo de ilanga libuyele endaweni yalo. Ulwahlulo lokuqala lomhla lwenziwa ngababingeleli baseYiputa ababelawula umzuzu wokubonakala kweenkwenkwezi, oku kwavumela ukwahlula ubusuku kwi-12 sub-periods yobude obulinganayo.

Ngenkulungwane ye-12, kwavela ama-sundials, ephawula ukuhamba kweeyure emini ngokuveza izithunzi. Ixesha lokucaca lahlulahlulwe laba ziiyure ezili-XNUMX.

Ukwahlulwa kweyure ibe yimizuzu engama-60 yimbopheleleko yamaBhabhiloni. Basebenzisa inkqubo yokubala esekelwe ekusetyenzisweni kwezandla. Ngobhontsi wesandla sokunene babebala, bephawula iphalanges nganye yeminye iminwe emine, xa kufuneka babale ngaphezu kwe-12 baphakamise umnwe wesandla sasekhohlo. Ngaloo nto babebala ukuya kutsho kuma-60.

Ngokuhamba kwexesha, iindlela ezahlukeneyo zenziwa ukurekhoda ukuhamba kwexesha usebenzisa iindlela ezifana nesithunzi esikhankanywe ngasentla, amandla omxhuzulane okanye isantya sokusetyenziswa kwekhandlela.

Iikhompyutha zineendlela ezimbini zokulinganisa ukuhamba kwexesha.. Enye isekwe kwihardware kwaye enye ikwisoftware.

Iwotshi yexesha lokwenyani (RTC)

Isebenza ngebhetri kwaye isebenza naxa ikhompyuter icinyiwe. Sithetha iwotshi ngengqiqo ebanzi ekubeni ingenawo amaqhosha, iinaliti okanye amanani akhokelwayo. Yisekethe edibeneyo eyinxalenye yebhodi yomama kwaye inoxanduva lokusebenzisa iwotshi yenkqubo. Loo sekethi ine-crystal oscillator esekelwe kwi-piezoelectric crystal.. Ikristale nganye inesakhiwo se-crystalline esenziwe ngepateni eqhelekileyo kunye nokuphindaphinda kwee-athomu. Ngokusebenzisa intsimi ngokusebenzisa i-crystal, isakhiwo sayo se-crystalline siphazamisekile kwaye, ngokususa intsimi, ibuyela kwimeko yangaphambili, ngaloo ndlela ivelisa umqondiso wombane kunye nesantya esichanekileyo.

iwotshi yenkqubo

Iwotshi yenkqubo isekelwe kulwazi lwewotshi yexesha lokwenyani kodwa Umntu ojongene nokulawula yi-kernel yenkqubo yokusebenza. Umsebenzi wayo kukuqwalasela, ukucwangcisa, kunye nokulungelelanisa imisebenzi, iinkqubo, kunye nokuphazamiseka.

Ayisiyo iwotshi kwisitayile sezicelo esizibonayo kwiselfowuni nokuba ayibonisi iiyure okanye imele ukuhamba kwexesha ngamanani.  Into eyenzayo kukurekhoda ukuhamba kwemizuzwana kunye ne-microseconds ngokukhupha iimpawu zedijithali.

Ingxaki ekufuneka isonjululwe kukunqongophala kongqamaniso phakathi kweewotshi zombini (ezisebenzisa iindlela ezahlukeneyo zokulinganisa ixesha) enye kwenye kunye nexesha lokwenyani. Yale, xa ikhompyuter iqala, iwotshi yenkqubo ifunda ixesha ukusuka kwiwotshi yexesha langempela kwaye isebenzise ifomula yokulungisa. Ke, ukuba ikhompyuter iqhagamshelwe kwi-Intanethi, imisela ixesha lokwenyani kwaye ilungelelanisa iwotshi yenkqubo ukuze ibonise ukuhamba kwexesha ngokufanelekileyo.

Uya kuqaphela kwiikhompyuter ezindala ukuba, ukuba akukho nxibelelwano lwe-Intanethi, ixesha, endaweni yelo lokwenyani, yimizuzu embalwa nje emva kokuba uyicimile. Oko kusonjululwa ngokutshintsha ibhetri enika amandla iwotshi yexesha lokwenyani.

Kwiikhompyuter zanamhlanje kunokwenzeka ukuba inkqubo yokusebenza ungayihoyi ikloko yexesha lokwenyani kwaye ubhekisele ngqo kumncedisi wexesha lomsebenzi womnatha.
