這篇文章主要介紹了golang時(shí)間字符串和時(shí)間戳轉(zhuǎn)換的案例，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧

1. 獲取當(dāng)前時(shí)間字符串和時(shí)間戳

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

更多時(shí)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(shí)間字符串解析成時(shí)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(dāng)天零點(diǎn)時(shí)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(diǎn)的時(shí)間戳，減去8個(gè)小時(shí)
  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(shí)區(qū)
  var Local *Location = &localLoc
以及UTC時(shí)區(qū)
  var UTC *Location = &utcLoc
還可以替換成指定時(shí)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(bǔ)充：Golang中獲取當(dāng)天0點(diǎn)的格式化時(shí)間

如下所示：

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

取當(dāng)天某個(gè)整點(diǎn)的時(shí)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(dāng)前時(shí)間戳(10位)
