1. 获取当前时间字符串和时间戳
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now().UTC()
// 显示时间格式： UnixDate = "Mon Jan _2 15:04:05 MST 2006"
fmt.Printf("%s\n", now.Format(time.UnixDate))
// 显示时间戳
fmt.Printf("%ld\n", now.Unix())
// 显示时分:Kitchen = "3:04PM"
fmt.Printf("%s\n", now.Format("3:04PM"))
}
更多时间格式
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. 时间字符串解析成时间格式
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. 获取当天零点时间戳
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返回早八点的时间戳，减去8个小时
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本地时区
var Local *Location = &localLoc
以及UTC时区
var UTC *Location = &utcLoc
还可以替换成指定时区
//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.
*/
补充：Golang中获取当天0点的格式化时间
如下所示：
EndDateLimit := time.Now().Format("2006-01-02 00:00:00")
取当天某个整点的时间戳
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()
本地当前时间戳(10位)
fmt.Println(time.Now().Unix()) //1468479251
本地当前时间戳(19位)
fmt.Println(time.Now().UnixNano()) //1468480006774460462
时间戳转时间
fmt.Println(time.Unix(1389058332, 0).Format("2006-01-02 15:04:05")) //2014-01-07 09:32:12
时间转时间戳
fmt.Println(time.Date(2014, 1, 7, 5, 50, 4, 0, time.Local).Unix())
