The display should use a $12-$hour clock and indicate whether it's AM or PM$.$ The application looks like

this:

Digital clock

Clock

$12$: $04$:$03PM$

To convert the computer's time from a $24-$hour clock to a $12-$hour clock, first check to see if the hours

value is greater than $12.$ If so$,$ subtract $12$ from the hours value and set the AM$/$PM value to $"$PM$".$ Also,

be aware that the hours value for midnight is $0.$

In the JavaScript file, note that four functions are supplied. The function that you

can use to select elements. The padSingleDigit$()$ function, that adds a leading zero to single digits

using a string method that you'll learn about in chapter $12.$ The start of a displayCurrentTime$()$

function. And the start of a DQMContentLoaded event handler.

In the displayCurrentTime$()$ function, add code that uses the Date object to determine the current

hour, minute, and second. Convert these values to a $12-$hour clock, determine the AM$/$PM value, and

display these values in the appropriate span tags.

In the DQMContentLoaded event handler, code a timer that calls the displayCurrentTime$()$ function

at $1$ second intervals. Also, make sure that the current time showws as soon as the page loads.
