這篇文章主要介紹了golang時間字符串和時間戳轉換的案例，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

1. 獲取當前時間字符串和時間戳

package main
import (
  "fmt"
  "time"
)
func main() {
  now := time.Now().UTC()
  // 顯示時間格式： UnixDate = "Mon Jan _2 15:04:05 MST 2006"
  fmt.Printf("%s\n", now.Format(time.UnixDate))
  // 顯示時間戳
  fmt.Printf("%ld\n", now.Unix())
  // 顯示時分:Kitchen = "3:04PM"
  fmt.Printf("%s\n", now.Format("3:04PM"))
}

更多時間格式

const (
    ANSIC    = "Mon Jan _2 15:04:05 2006"
    UnixDate  = "Mon Jan _2 15:04:05 MST 2006"
    RubyDate  = "Mon Jan 02 15:04:05 -0700 2006"
    RFC822   = "02 Jan 06 15:04 MST"
    RFC822Z   = "02 Jan 06 15:04 -0700" // RFC822 with numeric zone
    RFC850   = "Monday, 02-Jan-06 15:04:05 MST"
    RFC1123   = "Mon, 02 Jan 2006 15:04:05 MST"
    RFC1123Z  = "Mon, 02 Jan 2006 15:04:05 -0700" // RFC1123 with numeric zone
    RFC3339   = "2006-01-02T15:04:05Z07:00"
    RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00"
    Kitchen   = "3:04PM"
    // Handy time stamps.
    Stamp   = "Jan _2 15:04:05"
    StampMilli = "Jan _2 15:04:05.000"
    StampMicro = "Jan _2 15:04:05.000000"
    StampNano = "Jan _2 15:04:05.000000000"
)

2. 時間字符串解析成時間格式

package main
import (
  "fmt"
  "time"
)
func main() {
  timeStr := "2018-01-01"
  fmt.Println("timeStr:", timeStr)
  t, _ := time.Parse("2006-01-02", timeStr)
  fmt.Println(t.Format(time.UnixDate))
}

3. 獲取當天零點時間戳

方法1

package main
import (
  "fmt"
  "time"
)
func main() {
  timeStr := time.Now().Format("2006-01-02")
  t, _ := time.Parse("2006-01-02", timeStr)
  fmt.Println(t.Format(time.UnixDate))
  //Unix返回早八點的時間戳，減去8個小時
  timestamp := t.UTC().Unix() - 8*3600
  fmt.Println("timestamp:", timestamp)
}

方法2

package main
import (
  "fmt"
  "time"
)
func main() {
  now := time.Now()
  t, _ := time.ParseInLocation("2006-01-02", now.Format("2006-01-02"), time.Local)
  timestamp := t.Unix()
  fmt.Println(timestamp)
}
/*
time.Local本地時區(qū)
  var Local *Location = &localLoc
以及UTC時區(qū)
  var UTC *Location = &utcLoc
還可以替換成指定時區(qū)
  //func LoadLocation(name string) (*Location, error)
  loc, _ := time.LoadLocation("Europe/Berlin")
If the name is "" or "UTC", LoadLocation returns UTC. If the name is "Local", LoadLocation returns Local.
*/

補充：Golang中獲取當天0點的格式化時間

如下所示：

EndDateLimit := time.Now().Format("2006-01-02 00:00:00")

取當天某個整點的時間戳

now := time.Now().Unix()
muteEndTime := time.Date(time.Now().Year(), time.Now().Month(), time.Now().Day(), 8, 0, 0, 0, time.Local).Unix()
muteStartTime := time.Date(time.Now().Year(), time.Now().Month(), time.Now().Day(), 22, 0, 0, 0, time.Local).Unix()

本地當前時間戳(10位)
