Tipo de tempo HTML retorna alteração de tempo 24 horas para 12 horas
If your computer's system prefs are set to use a 24-hour clock, the browser will render the <input type="time"> element as --:-- (time range: 00:00–23:59). If you change your computer's syst prefs to use 12-hour, the output won't change until you quit and relaunch the browser.
