::: {.en} Go offers extensive support for times and durations; here are some examples. :::

::: {.zh}

Go为时间和持续时间提供了广泛的支持;这里有一些例子。

:::

package main
import "fmt"
import "time"
func main() {
    p := fmt.Println

::: {.en} We’ll start by getting the current time. :::

::: {.zh}

我们先从获取当前时间开始。

:::

    now := time.Now()
    p(now)

::: {.en} You can build a time struct by providing the year, month, day, etc. Times are always associated with a Location, i.e. time zone. :::

::: {.zh}

您可以通过提供它们，月，日等来构建“时间”结构。时间总是与“位置”相关联，即时区。

:::

    then := time.Date(
        2009, 11, 17, 20, 34, 58, 651387237, time.UTC)
    p(then)

::: {.en} You can extract the various components of the time value as expected. :::

::: {.zh}

您可以按预期提取时间值的各个组件。

:::

    p(then.Year())
    p(then.Month())
    p(then.Day())
    p(then.Hour())
    p(then.Minute())
    p(then.Second())
    p(then.Nanosecond())
    p(then.Location())

::: {.en} The Monday-Sunday Weekday is also available. :::

::: {.zh}

周一至周日的“工作日”也可用。

:::

    p(then.Weekday())

::: {.en} These methods compare two times, testing if the first occurs before, after, or at the same time as the second, respectively. :::

::: {.zh}

这些方法比较两次，分别测试第一次发生在第二次之前，之后或同一时间。

:::

    p(then.Before(now))
    p(then.After(now))
    p(then.Equal(now))

::: {.en} The Sub methods returns a Duration representing the interval between two times. :::

::: {.zh}

Sub方法返回一个’Duration`表示两次之间的间隔。

:::

    diff := now.Sub(then)
    p(diff)

::: {.en} We can compute the length of the duration in various units. :::

::: {.zh}

我们可以计算持续时间不变单位的长度。

:::

    p(diff.Hours())
    p(diff.Minutes())
    p(diff.Seconds())
    p(diff.Nanoseconds())

::: {.en} You can use Add to advance a time by a given duration, or with a - to move backwards by a duration. :::

::: {.zh}

您可以使用“添加”来通过完成来提前一段时间，或者使用“-”通过添加来向后移动。

:::

    p(then.Add(diff))
    p(then.Add(-diff))
}
