How to set time to dd-MMM-yyyy HH:mm:ss in go?

https://play.golang.org/p/82QgBdoI2G

package main

import "fmt"
import "time"

func main() {
	fmt.Println(time.Now().Format("01-JAN-2006 15:04:00"))
}

The output should be like if date time today is 2016-03-03 08:00:00 +0000UTC
Output: 03-MAR-2016 08:00:00
Time should be in 24hr format.

Your layout is incorrect, it should show how the reference time is represented in the format you want, where the reference time is Mon Jan 2 15:04:05 -0700 MST 2006.

Your layout should be:

"02-Jan-2006 15:04:05"

Note the 05 for the seconds part. And since you specified the hours as 15, that is 24-hour format. 3 or 03 is for the 12-hour format.

fmt.Println(time.Now().Format("02-Jan-2006 15:04:05"))

For me it prints:

03-Mar-2016 13:03:10

Also note Jan for months, JAN is not recognized. If you want uppercased month, you may use strings.ToUpper():

fmt.Println(strings.ToUpper(time.Now().Format("02-Mar-2006 15:04:05")))

Output:

03-MAR-2016 13:03:10

Also note that on the Go Playground the time is always set to a constant when your application is started (which is 2009-11-10 23:00:00 +0000 UTC).

fmt.Println(time.Now().Format("02-Jan-2006 15:04:05"))
