Go time.Now().UnixNano() convert to milliseconds?

by

The 2021 answer:

As of go v1.17, the time package added UnixMicro() and UnixMilli(), so the correct answer would be: time.Now().UnixMilli()

Original answer:

Just divide it:

func makeTimestamp() int64 {
    return time.Now().UnixNano() / int64(time.Millisecond)
}

Here is an example that you can compile and run to see the output

package main

import (
    "time"
    "fmt"
)

func main() {
    a := makeTimestamp()

    fmt.Printf("%d \n", a)
}

func makeTimestamp() int64 {
    return time.Now().UnixNano() / int64(time.Millisecond)
}
