How to parse a milliseconds-since-epoch timestamp string in Go?

2021 update: you can use UnixMilli to parse from the integer. This would improve the accepted answer to:

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

    return time.UnixMilli(msInt), nil
}

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
}
