问题

我看到代码中的时间格式是"0102150405"，但我不知道这是什么格式。有人知道吗？ 😊

time.Now().UTC().Format("0102150405")

time.Now().UTC().Format("0102150405")

（2006年1月2日15:04:05，格林尼治标准时间西七小时）。

该值被记录为名为Layout的常量，如下所示。

作为Unix时间，这是1136239445。由于MST是GMT-0700，
Unix date命令将打印出参考时间：
星期一，2006年1月2日15:04:05 MST

您可以使用它来格式化您获得的time值。

0102150405表示想要将time.Now()格式化为类似于"${month}${day}${hour}${minute}${second}"的string。

(January 2, 15:04:05, 2006, in time zone seven hours west of GMT).

That value is recorded as the constant named Layout, listed below.

As a Unix time, this is 1136239445. Since MST is GMT-0700,
the reference would be printed by the Unix date command as:
Mon Jan 2 15:04:05 MST 2006

You can use it to format the `time` value you got.

`0102150405` means want to format `time.Now()` as `string` like `"${month}${day}${hour}${minute}${second}"`.

Text in the layout string that is not recognized as part of the reference time is echoed verbatim during Format and expected to appear verbatim in the input to Parse.
