JavaScript | date.toLocaleTimeString()

The date.toLocaleTimeString() is an inbuilt function in JavaScript which is used to fetch the time from a given Date object.

 DateObj.toLocaleTimeString()

In the above syntax, DateObj is a valid Date object created using Date() constructor from which we want to fetch the time.

<script>
  
  // Here a date has been assigned
  // while creating Date object
  var dateobj = new Date('July 16, 2018 05:35:32');
  
  // time from above date object is 
  // being extracted using toLocaleTimeString()
  var B = dateobj.toLocaleTimeString();
  
  // Printing time
  document.write(B);
    
</script>

chevron_right


Output:



5:35:32 

Errors and Exceptions:

  • Example 1: The date of the month should lie in between 1 to 31 because none of the months have the date greater than 31 that is why it returns Invalid Date because the date for the month does not exist. Hence, Year will not have existed when the date of the month is given as 36 i.e, greater than 31.

    Output:

    Invalid Date
    
  • Example 2: If nothing as parameter is given to the Date() constructor the current date is passed in Date object and hence toLocaleTimeString() will return current time.
