如何在Go中解析毫秒级以来的时间戳字符串?

I've got a string with milliseconds since the epoch (it came originally from a java.lang.System.currentTimeMillis() call). What's the right way to convert this string into a human readable timestamp string in Go?

Looking at the time package I see the Parse function, but the layouts all seem to be normal timezone-based times. Once into a Time object, I can use Format(Time.Stamp) to get the output I want, but I'm not clear on how to get the string into a Time object.

    The format string does not support milliseconds since the epoch, so you need to parse manually. For example:

    func msToTime(ms string) (time.Time, error) {
        msInt, err := strconv.ParseInt(ms, 10, 64)
        if err != nil {
            return time.Time{}, err
        }
    
        return time.Unix(0, msInt*int64(time.Millisecond)), nil
    }
