Timedatectl uye Hwclock: Mirairo yekumisikidza zuva uye nguva muLinux

Timedatectl uye Hwclock Iwo maviri anobatsira rairo kugadzirisa iyo nguva (zuva uye nguva), mune yedu GNU / Linux Maitiro Ekushandisa.

Nguva zhinji kana uchiisa nekushandisa GNU / Linux Inoshanda Sisitimu, vamwe vanogona kunge vakaonga kuti kana uchitanga nguva yega yega, chikamu chevashandisi munzvimbo inoonekera kana kuburikidza nechiteshi, iyo nguva (zuva uye nguva) Del Operating system yekomputa shanduko (mismatch). Mune zvimwe zviitiko, zvinowanzo shanduka kana iwe uine gadziriso ye bhutsu mbiri (mbiri bhutsu) uye kushandiswa kwe Mashandiro Sistems yakaiswa.

Muchiitiko chekutanga chakatsanangurwa, ndiko kuti, kushandisa chete GNU / Linux, kazhinji dambudziko rinogadziriswa kwechinguva, ndokuti, kwete kugadziriswa, kugadzirisa wachi yekumisikidza application graphic kana kuburikidza terminal uchishandisa raira "zuva".

Muchiitiko chechipiri, ndiko kuti, kushandisa 2 kana kupfuura Maitiro ekushanda zvakasiyana, kazhinji GNU / Linux uye Windows, dambudziko rinowanzo gadziriswa kwechinguva nekuisa nemaoko nguva kubva kune yekutanga kusvika kune nguva (zuva uye nguva) yechipiri, uye mune dzimwe nguva panguva ya Bios yekomputa.

Dambudziko

El nguva mismatch dambudziko nhema, nenzira iyo yedu GNU / Linux Maitiro Ekushandisa ivo vanoita zuva nenguva. Ndokunge, hazvina kufanana nemabatirwo ainoitwa Maitiro ekushanda zvakasiyana zvachose senge Windows, kunyange hongu sevamwe, senge, MacOS.

En GNU / Linux kana MacOS, pateni inoshandiswa UTC (Yakabatanidzwa Yese Nguva Nguva) kuseta iyo nguva yakafanana, nepo muWindows kwete. Windows inofungidzira kuti komputa inochengeta chaiyo uye yakagadziridzwa nguva mu Motherboard Hardware wachi, ndiko kuti, mu Bios. Sezvo, iyo Clock uye / kana BIOS iwe unofanirwa kuteedzera iyo yakapfuura nguva, kunyangwe kana komputa yadzima.

Naizvozvo, nekutadza, Windows inogara ichifunga kuti nguva chaiyo inochengetwa mu Yemunharaunda nguva (Clock / BIOS) kubva pakombuta, apo GNU / Linux, sezvatakataridza, zvinotora kuti nguva yakachengetwa mu UTC nguva, izvo zvinokonzeresa kuti cyclical time lag yakamirirwa nekushandisa neimwe nzira iyo 2. Naizvozvo, mhinduro ine musoro ndeyekugadzirisa nenzira kwayo iyo Yemunharaunda nguva (Clock / BIOS) kubva pakombuta, uye gadzirisa yega yega Sisitimu Yekushandisa kuti utaure nayo kuti uwiriranise nguva inoratidzwa kumushandisi.

Timedatectl uye Hwclock Mirairo

Kune mirairo yekugadzirisa iri dambudziko, ndiko kuti, kumisikidza izvo GNU / Linux kutaurirana nemidziyo (Clock / BIOS) kubva pakombuta yako uye inowirirana nayo, ku ratidza mushandisi panguva imwe chete, sezvaunoita iwe Windows.

Asati aurayiwa, kurongeka kwakanaka kweiyo nguva (zuva uye nguva) in the BiosMushure mekuita iwo murairo, zviri nani kutanga uye kuona kuti inoramba isina kuchinja, kutanga mu GNU / Linux Inoshanda Sisitimu uyezve mu Bios.

Iyi mirairo ndeiyi:

Nguva yakatarwa

Uyu murairo wazvino wakakosha, kune avo GNU / Linux Distros iyo yavakaisa Systemd Chemhondoro Kutanga maitiro 1 (PID 1), Semuyenzaniso, DEBIAN GNU / Linux. Sezvo, iko kushanda kunopihwa ino sisitimu uye masevhisi maneja.

Kuti uwane iwo murairo, tendera GNU / Linux kutaurirana nemidziyo (Clock / BIOS) kubva pakombuta uye wirirana nayo, unotevera kuraira unofanirwa kuitiswa:

sudo timedatectl set-local-rtc 1

Kuti uwane rumwe ruzivo nezve uyu murairo, sarudzo «set-local-rtc [BOOL]»Uye vamwe, nezve DEBIAN GNU / Linux, unogona kuwana iyo Chinyorwa chepamhepo (Manpages) yemapakeji nemirairo zvakafanana, pane zvinotevera link. Kana verenga yako yemuno murume peji nekumhanya «man timedatectl".

hwclock

Uyu unoshamisa uye uchiri kuraira ikozvino, yakakosha kune ese marudzi e GNU / Linux Distros, sezvo zvisingatsamiri pa Yakarongwa, kana kubva kune chero imwe system uye mutariri webasa.

Kuti uwane iwo murairo, tendera iyo Operating system GNU / Linux kutaurirana nemidziyo (Clock / BIOS) kubva pakombuta uye wirirana nayo, ndiko kuti, gadzira iyo nguva yakafanana pane iyo BIOS, unotevera kuraira unofanirwa kuitiswa:

sudo hwclock -w o sudo hwclock --systohc

chitsamba: Yenyaya yakapesana, ndiko kuti, kana pachinzvimbo iwe uchida kuwiriranisa kumashure (gadzira iyo yazvino BIOS nguva pane iyo Inoshanda Sisitimu) ipapo unogona kushandisa rairo «hwclock -s»Kana iwo murairo «hwclock --hctosys«.

Kuti uwane rumwe ruzivo nezve uyu murairo, sarudzo «-w»Uye vamwe nezve DEBIAN GNU / Linux, unogona kuwana iyo Chinyorwa chepamhepo (Manpages) yemapakeji nemirairo zvakafanana, pane zvinotevera link. Kana verenga yako yemuno murume peji nekumhanya «man hwclock".

Kubva ikozvino zvichienda mberi, paunomira kushandisa iyo UTC pateni yezuva nenguvandiko kuti, kana uchishandisa iyo nguva (zuva uye nguva) Del Bios nokuti GNU / Linux kana akati wandei Maitiro ekushanda, iro dambudziko neiyo nguva yekumisikidza ye Hardware ichadzivirirwa uye maese masystem anogara aine nguva imwechete, pasina lags.

Imwe nzira yekumisikidza yekumisikidza zuva uye nguva yeiyo GNU / Linux Inoshanda Sisitimu uye sync ine iyo Bios kubva pakombuta, uchishandisa rairo «date»Uye«hwclock»Izvi zvinotevera:

Dzorera rairo yekuraira kubva ku mudzi wechikamu kuseta zuva 08:00 musi waKurume 07, 2020.

• date --set "2020-03-07 08:00"
• hwclock --set --date="`date '+%D %H:%M:%S'`"
