golang时间字符串和时间戳转换的案例

1. 获取当前时间字符串和时间戳

package mainimport (  "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 mainimport (  "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 mainimport (  "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 mainimport (  "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())
