Dear @Saban

Until there isn't an official MDB Time Format, try use this:

<div class="container">
  <div class="row">
    <div class="col-sm-6">
      <label for="appt">Choose a time for your meeting:</label>

      <input
        mdbInput
        type="time"
        id="appt"
        name="appt"
        min="00:00"
        max="23:59"
        class="form-control"
      />
    </div>
  </div>
</div>

Or use our time picker: https://mdbootstrap.com/docs/angular/forms/time-picker/

Best Regards, Bartosz.
