Go - Time
Go对时间操作有很好的支持。 Unix纪元时间用作时间操纵的参考。
我们可以使用时间包中提供的Date方法来构建时间对象。该软件包包含诸如year()，month()，day()，location()等方法。
我们通过使用时间对象来调用这些方法。
Go时间示例1
package main import "fmt" import "time" func main() { p := fmt.Println present := time.Now()// 当前时间 p(present) DOB := time.Date(1993, 02, 28, 9,04,39,213 ,time.Local) fmt.Println(DOB) fmt.Println(DOB.Year()) fmt.Println(DOB.Month()) fmt.Println(DOB.Day()) fmt.Println(DOB.Hour()) fmt.Println(DOB.Minute()) fmt.Println(DOB.Second()) fmt.Println(DOB.Nanosecond()) fmt.Println(DOB.Location()) fmt.Println(DOB.Weekday()) fmt.Println(DOB.Before(present)) fmt.Println(DOB.After(present)) fmt.Println(DOB.Equal(present)) diff := present.Sub(DOB) fmt.Println(diff) fmt.Println(diff.Hours()) fmt.Println(diff.Minutes()) fmt.Println(diff.Seconds()) fmt.Println(diff.Nanoseconds()) fmt.Println(DOB.Add(diff)) fmt.Println(DOB.Add(-diff)) }
