Unix Timestamp ilbiriqsi iyo milisekand: maxaa taariikhdu 1970 u muujisaa

Waxaad u beddeshay timestamp taariikh waxaadna ku dhacday Janaayo 1970. Saacaddu dhif iyo naadir bay jabtaa. Lambarka waxaa loo akhriyay milisekand markii uu ku kaydsanaa ilbiriqsi—ama lidkeeda.

Waa maxay Unix timestamp?

Unix timestamp wuxuu cabbiraa wakhtiga laga soo bilaabo Unix epoch: 1970-01-01 00:00:00 UTC. Caadi ahaan wuxuu isticmaalaa ilbiriqsi dhammaystiran. Isla daqiiqaddaas waxaa lagu kaydin karaa milisekand (ilbiriqsi × 1,000). Lambarka laftiisu ma tilmaamo unugga.

Ilbiriqsi iyo milisekand: kala duwanaanshaha ×1,000

Hal ilbiriqsi waa 1,000 milisekand. Isbarbardhig 1720000000 iyo 1720000000000. Haddii kan hore yahay ilbiriqsi kan danbe milisekand, waa isla daqiiqad. Kan hore u akhri milisekand, taariikhdu waxay u booddaa 1970.

Natiijooyinkan UTC waxaa laga xisaabiyay lambarrada kor ku xusan, maaha qiyaas.

Qiime	Unug suurtagal ah	Fasiraad (UTC)
1720000000	Ilbiriqsi	Taariikh casri ah marka loo akhriyo ilbiriqsi: 2024-07-03 09:46:40 UTC
1720000000000	Milisekand	Isla daqiiqadda marka loo akhriyo milisekand: 2024-07-03 09:46:40 UTC
1720000000 sidii milisekand	Unug qaldan	Taariikh ku dhow 1970: 1970-01-20 21:46:40 UTC

Maxaa timestamp-kaygu 1970 u muujinayaa?

Haddii qiime ilbiriqsi loo qaato milisekand, lambarku waa 1,000 jeer ka yar sidii loo baahnaa. JavaScript markaas waxay tiriyaa muddo gaaban oo keliya ka dib Unix epoch, sidaas darteed taariikhdu waxay ku sii jirtaa 1970:

const seconds = 1720000000;

new Date(seconds);
// 1970-01-20 21:46:40 UTC

new Date(seconds * 1000);
// 2024-07-03 09:46:40 UTC

Taariikhdaas 1970 waa epoch iyo qiyaastii laba toddobaad. Ku dhufo ilbiriqsiyada 1,000 ka hor intaadan u dhiibin Date.

Ma 10 lambar waa ilbiriqsi 13-na milisekand?

Taariikhaha casriga ah, 10 lambar inta badan waa ilbiriqsi, 13 inta badan milisekand. Waa tilmaan degdeg ah, ma aha xeer xaqiijin. Tirada lambarada way isbeddeshaa iyadoo wakhtiga kala duwan yahay; API qaar waxay kaydiyaan mikrosekand ama nanosekand. Unugga ku xaqiiji dukumentiga ama taariikh macno leh.

Maxaa tan ugu dhacda inta badan JavaScript

JavaScript dhexdeeda, Date nambar waa milisekand laga soo bilaabo epoch. Backend badan, kaydad xog iyo qalab Unix ayaa weli kaydiya ilbiriqsi. In ilbiriqsi toos loogu dhiibo Date waa khalad caadi ah:

const unixSeconds = 1720000000;

const wrong = new Date(unixSeconds);
const correct = new Date(unixSeconds * 1000);

wrong wuxuu ku dhow yahay 1970 (1970-01-20 21:46:40 UTC). correct waa daqiiqadda casriga (2024-07-03 09:46:40 UTC).

Nidaamyada kale waxay isticmaalaan unugyo kala duwan

Luqado, API iyo kaydad kale waxay isticmaali karaan ilbiriqsi ama milisekand. Qaar waxay kaydiyaan mikrosekand ama nanosekand. Ha u malayn in luqad mar walba unug keliya isticmaasho—eeg dukumentiga. Haddii lambarku ku jiro JSON, Habee oo isbarbar dhig JSON wuxuu ka dhigaa goobta mid la akhrin karo; unugga weli ma sheego.

Sidee u ogaadaa unugga timestamp-kaygu isticmaalo?

Baadhitaanadan u samee si kala horreeya. Tirada lambarada keliya kuma filna.

1. Eeg dukumentiga API ama kaydka xogta.
2. Eeg tirada lambarada ee qiyaasta.
3. Isbarbardhig qiimaha iyo timestamp casri oo macquul ah.
4. Tijaabi qiimaha sidii ilbiriqsi iyo sidii milisekand.
5. Hubi in taariikhda soo baxday macno leedahay.

Haddii fasiraad ku dhacdo 1970 tan kalena ku dhacdo taariikh aad aqoonsato, sababtu waa unug aan iswaafaqin.

Khaladaadka caadiga ah ee Unix timestamp

• Ilbiriqsi loo fasiray milisekand. Taariikhdu waxay u dumtaa 1970, sida tusaalaha kore.
• Milisekand loo fasiray ilbiriqsi. Taariikhdu waxay u booddaa mustaqbalka fog, ama beddelku wuu fashilmaa.
• Ku dhufo 1,000 laba jeer. Qiime horay u ahaa milisekand wuxuu noqdaa mid aad u weyn taariikhuna waxay u booddaa qarniyo hore.
• U qaybi 1,000 laba jeer. Qiimaha ilbiriqsi mar kale wuu yaraadaa, mar kale wuxuu ku dhow yahay 1970.
• Eedaynta aagga saacadda. Aaggu wuxuu dhaqaajin karaa saacado ama maalinta jadwalka. Ma geeyo timestamp casri 1970.
• Qaadashada xarig taariikh qaabaysan sidii Unix timestamp. Qiime sida 2024-07-03T09:46:40Z ma aha lambar epoch. U kala saar sidii taariikh, ma aha ilbiriqsi.

Aagga saacadda ma keenaa dhibaatada 1970?

Caadi ahaan maya. Aagga saacadda wuxuu beddeli karaa saacadda la muujiyay, habeenbadhkana agteeda taariikhda jadwalka. Ma beddelo Unix timestamp casri 1970. Haddii natiijadu tahay 1970, marka hore eeg ilbiriqsi iyo milisekand.

Beddel oo hubi Unix timestamp

FAQ

Maxaa Unix timestamp-kaygu 1970 u muujinayaa?

Inta badan waa ilbiriqsi loo akhriyay milisekand. JavaScript waxay maamushaa lambar aad u yar, sidaas darteed taariikhdu waxay fadhiisataa isla markiiba 1970-01-01 00:00:00 UTC ka dib. Ku dhufo ilbiriqsiyada 1,000 oo mar kale beddel.

Unix timestamps ma ilbiriqsi mise milisekand?

Caadi ahaan ilbiriqsi. API-yada websaydhka badan iyo JavaScript Date waxay isticmaalaan milisekand. Had iyo jeer eeg waxa nidaamkaasi dukumeentiyeeyo. Qaar waxay isticmaalaan mikrosekand ama nanosekand.

Sidee ugu beddelaa ilbiriqsi milisekand?

Ku dhufo 1,000. 1720000000 ilbiriqsi waa 1720000000000 milisekand. Jihada kale, u qaybi 1,000.

Maxaa JavaScript Date ugu isticmaalaa milisekand?

Timestamp-ka nambar ee Date ee JavaScript waxaa lagu qeexay milisekand laga soo bilaabo Unix epoch. Sidaas darteed new Date(unixSeconds) waa khalad marka unixSeconds yahay ilbiriqsi Unix.

Timestamp 10 lambar ah mar walba ma ilbiriqsi baa?

Maya. Taariikhaha casriga ah inta badan waa, 13 lambar inta badan milisekand. Tirada lambarada waa tilmaan, ma aha xeer. Ku xaqiiji dukumentiga ama taariikh macno leh.

Unix timestamp ma ku jiraa aag saacadeed?

Maya. Unix timestamp waa daqiiqad laga tiriyo 1970-01-01 00:00:00 UTC. Aagagga saacadda waxay saameeyaan muujinta, ma aha lambarka laftiisa.
