Go by Example: Epoch

Dasturlardagi keng tarqalgan talab Unix epochdan beri o’tgan soniyalar, millisoniyalar yoki nanosoniyalar sonini olishdir. Buni Go’da qanday qilish quyida ko’rsatilgan.

 
package main
 
import (
    "fmt"
    "time"
)
 
func main() {

Unix epoch’dan beri o’tgan vaqtni mos ravishda soniya, millisoniya yoki nanosoniyalarda olish uchun time.Now ni Unix, UnixMilli yoki UnixNano bilan ishlating.

 
    now := time.Now()
    fmt.Println(now)
 
    fmt.Println(now.Unix())
    fmt.Println(now.UnixMilli())
    fmt.Println(now.UnixNano())

Shuningdek, epoch’dan beri o’tgan butun sonli soniya yoki nanosoniyalarni mos keluvchi time ga aylantirishingiz mumkin.

 
    fmt.Println(time.Unix(now.Unix(), 0))
    fmt.Println(time.Unix(0, now.UnixNano()))
}
 
$ go run epoch.go

Keyingi navbatda biz vaqtga oid yana bir vazifani ko’rib chiqamiz: vaqtni tahlil qilish (parsing) va formatlash.

Keyingi misol: .
