time formatting _ golang

Go supports time formatting and parsing via pattern-based layouts

package main

import (
    "fmt"
    "time"
)

func main() {

    p := fmt.Println

    t := time.Now()
    p(t.Format(time.RFC3339))

    t1, e := time.Parse(time.RFC3339, "2012-11-01T22:08:41+00:00")
    p(t1)
    p(e)

    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"))
    form := "3 04 PM"
    t2, e := time.Parse(form, "8 41 PM")
    p(t2)

    fmt.Printf("%d-%02d-%02dT%02d:%02d:%02d-00:00\n", t.Year(), t.Month(), t.Day(), t.Hour(), t.Minute(), t.Second())

    ansic := "Mon Jan _2 15:04:05 2006"
    _, e = time.Parse(ansic, "8:41PM")
    p(e)

}
