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" import "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 dive 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.
