Go by Example: Epoch

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() {
Use `time.Now` with `Unix` or `UnixNano` to get elapsed time since the Unix epoch in seconds or nanoseconds, respectively.	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)) }

	$ go run epoch.go 2012-10-31 16:13:58.292387 +0000 UTC 1351700038 1351700038292 1351700038292387000 2012-10-31 16:13:58 +0000 UTC 2012-10-31 16:13:58.292387 +0000 UTC
Next we’ll look at another time-related task: time parsing and formatting.
