Go语言的时间格式化与其他语言不同而独特。Go语言不使用传统的日期格式来打印日期，而是使用参考日期20060102150405，这看起来毫无意义，但实际上有其原因，因为它对应于Posix date命令中的1 2 3 4 5 6：
Mon Jan 2 15:04:05 -0700 MST 2006
0 1 2 3 4 5 6
时区是7，但它位于中间，所以最终的格式类似于1 2 3 4 5 7 6。
如果你正在从strftime格式过渡，可以使用这个在线转换工具。
有趣的历史参考：https://github.com/golang/go/issues/444
time包还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" // 带数字时区的RFC822
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" // 带数字时区的RFC1123
RFC3339 = "2006-01-02T15:04:05Z07:00"
RFC3339Nano = "2006-01-02T15:04:05.999999999Z07:00"
Kitchen = "3:04PM"
// 方便的时间戳。
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"
)
你可以像这样使用它们：
t := time.Now()
fmt.Println(t.Format(time.ANSIC))
英文:
Go's time formatting 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:
Mon Jan 2 15:04:05 -0700 MST 2006
0 1 2 3 4 5 6
The timezone is 7 but that sits in the middle, so in the end the format resembles 1 2 3 4 5 7 6.
This online converter is handy, if you are transitioning from the strftime format.

The time package provides handy constants as well:
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:
t := time.Now()
fmt.Println(t.Format(time.ANSIC))

请问您需要将以下内容翻译成中文吗？
"See https://golang.org/pkg/time/#pkg-constants It is the time "01/02 03:04:05PM '06 -0700" Because each component has a different number (1, 2, 3, etc.), it can determine from the numbers what components you want."
