Time to Unix Epoch

Post Example

by yhuang Go fmt.Println time.Unix fmt time time.Now

A common requirement in programs is getting the number of seconds, milliseconds, or nanoseconds since the Unix epoch. Here’s how to do it in Go.

package main

import (
    "fmt"
    "time"
)

func main() {

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

    // Note that there is no UnixMillis, so to get the milliseconds since epoch
    // you'll need to manually divide from nanoseconds.
    millis := nanos / 1000000
    fmt.Println(secs)
    fmt.Println(millis)
    fmt.Println(nanos)

    // You can also convert integer seconds or nanoseconds since the epoch into the corresponding time.
    fmt.Println(time.Unix(secs, 0))
    fmt.Println(time.Unix(0, nanos))
}
