Obtaining a Unix Timestamp in Go Language (current time in seconds since epoch)

问题

I have some code written in Go which I am trying to update to work with the latest weekly builds. (It was last built under r60). Everything is now working except for the following bit:

 if t, _, err := os.Time(); err == nil {
   port[5] = int32(t)
 }

Any advice on how to update this to work with the current Go implementation?

回答1:

import "time"
...
port[5] = int32(time.Now().Unix())

回答2:

If you want it as string just convert it via strconv:

package main

import (
    "fmt"
    "strconv"
    "time"
)

func main() {
    timestamp := strconv.FormatInt(time.Now().UTC().UnixNano(), 10)
    fmt.Println(timestamp) // prints: 1436773875771421417
}

Another tip. time.Now().UnixNano()(godoc) will give you nanoseconds since the epoch. It's not strictly Unix time, but it gives you sub second precision using the same epoch, which can be handy.

Edit: Changed to match current golang api
