Go by Example 中文：时间
|
Go 对时间和时间段提供了大量的支持；这里是一些例子。 |
|
package main
|
|
import "fmt"
import "time"
|
|
func main() {
p := fmt.Println
|
|
|
得到当前时间。 |
now := time.Now()
p(now)
|
|
通过提供年月日等信息，你可以构建一个 |
then := time.Date(
2009, 11, 17, 20, 34, 58, 651387237, time.UTC)
p(then)
|
|
你可以提取出时间的各个组成部分。 |
p(then.Year())
p(then.Month())
p(then.Day())
p(then.Hour())
p(then.Minute())
p(then.Second())
p(then.Nanosecond())
p(then.Location())
|
|
输出是星期一到日的 |
p(then.Weekday())
|
|
这些方法来比较两个时间，分别测试一下是否是之前，之后或者是同一时刻，精确到秒。 |
p(then.Before(now))
p(then.After(now))
p(then.Equal(now))
|
|
方法 |
diff := now.Sub(then)
p(diff)
|
|
我们计算出不同单位下的时间长度值。 |
p(diff.Hours())
p(diff.Minutes())
p(diff.Seconds())
p(diff.Nanoseconds())
|
|
你可以使用 |
p(then.Add(diff))
p(then.Add(-diff))
}
|
