Here is a code that accepts the time in the format hh:mm. If the user enters the time in wrong format, it displays the error message.

<html>
<script language="JavaScript">
 function check(timeStr) {
 var regex = /^(\d{1,2}):(\d{2})?$/;
 var timArr = timeStr.match(regex);
 if (timArr == null) {
 alert("Time is not in a valid format.");
 document.frm.timetext.value="";
 return false;
 }
hour = timArr[1];
minute = timArr[2];
if (hour < 0  || hour > 23) {
alert("Hour must be between 1 and 12. (or 0 and 23 for military time)");
document.frm.timetext.value="";
return false;
}
if (minute<0 || minute > 59) {
alert ("Minute must be between 0 and 59.");
document.frm.timetext.value="";
return false;
}
return false;
}
</script>
<form name="frm">
      Time (HH:MM)
      <input type="text" name="timetext">
      <input type="button" value="Check" onclick="return check(document.frm.timetext.value);">
      </form>
</html>
