Format Time in Go

package main

import (
    "fmt"
    "time"
)

func main() {
    p := fmt.Println

    // Here's a basic example of formatting a time according to RFC3339,
    // using the corresponding layout constant.
    t := time.Now()
    p(t.Format(time.RFC3339))

    // Layouts must use the reference time Mon Jan 2 15:04:05 MST 2006 to show the pattern
    // with which to format a given time/string.
    p(t.Format("3:04PM"))
    p(t.Format("Mon Jan _2 15:04:05 2006"))
    p(t.Format("2006-01-02T15:04:05.999999-07:00"))

    // For purely numeric representations you can also use standard string formatting
    // with the extracted components of the time value.
    fmt.Printf("%d-%02d-%02dT%02d:%02d:%02d-00:00\n",
        t.Year(), t.Month(), t.Day(),
        t.Hour(), t.Minute(), t.Second())
}
