Store AM/PM from time input in local storage JavaScript

I'm creating a website that users need to put there check in time in time input and store it to local storage. I can only store the time but not the AM/PM. Why I can't store AM/PM on local storage from my time input?

<input type="time" class="form-control" id="txtcheckintime" name="checkintime" required="">    <script>        function passvalues(){          var checkintime=document.getElementById("txtcheckintime").value;          localStorage.setItem("checkintime", checkintime);              return true;    }  </script>
