4.2 时间格式转为字符串格式

package main

import (
    "fmt"
    "time"
)

func main() {
    tTime := time.Date(2017, time.March, 5, 8, 5, 2, 0, time.Local)

    // The formatting is done
    // with use of reference value
    // Jan 2 15:04:05 2006 MST
    fmt.Printf("tTime is: %s\n", tTime.Format("2006/1/2"))

    fmt.Printf("The time is: %s\n", tTime.Format("15:04"))

    //The predefined formats could
    // be used
    fmt.Printf("The time is: %s\n", tTime.Format(time.RFC1123))

    // The formatting supports space padding
    //only for days in Go version 1.9.2
    fmt.Printf("tTime is: %s\n", tTime.Format("2006/1/_2"))

    // The zero padding is done by adding 0
    fmt.Printf("tTime is: %s\n", tTime.Format("2006/01/02"))

    //The fraction with leading zeros use 0s
    fmt.Printf("tTime is: %s\n", tTime.Format("15:04:05.00"))

    //The fraction without leading zeros use 9s
    fmt.Printf("tTime is: %s\n", tTime.Format("15:04:05.999"))

    // Append format appends the formatted time to given
    // buffer
    fmt.Println(string(tTime.AppendFormat([]byte("The time is up: "), "03:04PM")))
}
