Timezone 'Z' not parsed for time string with milliseconds after period

[zifengyu]

'Z' is not parsed after timePeriod '.'. In below sample, the timezone is not detected and ParseIn will have incorrect result.

func main() {
	loc, _ := time.LoadLocation("Asia/Shanghai")
	inputs := []string{
		"1985-04-12T23:20:50Z",
		"1985-04-12T23:20:50.52Z"}
	for _, in := range inputs {
		t, _ := dateparse.ParseIn(in, loc)
		fmt.Println(t)
	}
}
