如何在Go中检测时间？

I need to parse the date_id field from emails headers. However these seem to have slightly different layouts so I've started to build a switch case/block . I'm wondering if that's really the way to fix this issue.

        case strings.Contains(h.Headers[bk].Date, "(CEST)"):
            layout = "Mon, 02 Jan 2006 15:04:05 -0700 (MST)"
        case strings.Contains(h.Headers[bk].Date, "(EDT)"):
            layout = "Mon, 02 Jan 2006 15:04:05 -0700 (MST)"
        default:
            layout = "Mon, 02 Jan 2006 15:04:05 -0700"
        }

You could use mail.Header and simply call .Date() on it.

Another option is to read the code starting from line 70 and write your own function.
