Go by Example 中文版: 时间
|
Go 为时间（time）和时间段（duration）提供了大量的支持；这儿有是一些例子。 |
|
 
package main |
|
import ( "fmt" "time" ) |
|
func main() { p := fmt.Println |
|
|
从获取当前时间时间开始。 |
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())
|
|
支持通过 |
p(then.Weekday())
|
|
这些方法用来比较两个时间，分别测试一下是否为之前、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)
|
|
我们可以用各种单位来表示时间段的长度。 |
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))
}
|
