In Go, the current time can be determined using time.Now(), provided by the .

在Go中，可以使用提供的time.Now()确定当前时间。

t := time.Now()

This will print the system local time. Want UTC instead? append .UTC():

这将打印系统本地时间。 需要UTC吗？ 附加.UTC() ：

The time can be formatted using the time.Format() method:

可以使用time.Format()方法格式化时间：

t := time.Now().UTC()

Want the timestamp?

需要时间戳吗？

t := time.Now().Unix()

使用自定义格式 (Use a custom format)

An example of formatting with a custom format is:

使用自定义格式进行格式化的示例如下：

fmt.Println(t.Format("2006-01-02 15:04:05"))

That 2006-01-02 15:04:05 string looks strange, isn’t it? It’s not like it’s 2006 now! But it will print (at the time of writing) 2017-01-16 12:53:51

那2006-01-02 15:04:05字符串看起来很奇怪，不是吗？ 现在不像是2006年！ 但是它将打印(在撰写本文时) 2017-01-16 12:53:51

If you’re new to Go, this will sound very strange.

如果您不熟悉Go，这听起来很奇怪。

Here’s the explanation: Go’s time formatting is unique and different than what you would do in other languages. Instead of having a conventional format to print the date, Go uses the reference date 20060102150405 which seems meaningless but actually has a reason, as it’s 1 2 3 4 5 6 in the Posix date command:

解释如下：Go的时间格式是独特的，并且与其他语言的格式不同。 Go没有使用常规格式来打印日期，而是使用了参考日期20060102150405 ，该日期似乎没有意义，但实际上是有原因的，因为Posix date命令中的date是1 2 3 4 5 6 ：

Mon Jan 2 15:04:05 -0700 MST 20060   1   2  3  4  5              6

The timezone in the middle would have been the 7 (not really sure why they didn’t pick Mon Jan 2 03:04:05 -0600 MST 2007, by the way)

中间的时区应该是7 (顺便说一下，不确定他们为什么不选择Mon Jan 2 03:04:05 -0600 MST 2007 )

使用格式常量 (Use a format constants)

Go provides in the time package some handy constants for commonly used formats:

Go在time包中为常用格式提供了一些方便的常量：

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")

You can use them like this:

您可以像这样使用它们：

t := time.Now()fmt.Println(t.Format(time.ANSIC))
