Thanks for the video! The only problem I encountered was that I noticed was that the seconds seemed to be advancing much too rapidly. So after a little research and tinkering, I found that adding 10 milliseconds after the function name in setInterval took care of the issue:
buttonStart.onclick = function() {
interval = setInterval(startTimer, 10);
}

WOW finally a tutorial what starts entire process from zero and does not require downloading some "base" code. Love it! Thank you. It was so understandable for someone who barely knows javascript.

Nice tutorial, easy to follow. But, there is one problem. When I open new tab, it stops counting, until I switch back to that tab. Is there a way to solve this problem?

[rosetoiyojohn]

A nice one
But why did you do this:setinterval(starttimer)
And then clearinterval(interval)
Why is the use of the start timer and interval there
Edit: if the start button is clicked more than once the stop button doesn't end it again
Why

Thanks so much for this video. It's so simple and straightforward....
Also the stop button doesn't work for me

Mr GOWtham everything is working great, even stopwatch is working, but i cant make all 3 buttons align in center, this problem is coming, do you have source code for HTML for this.

[ragunathans]

For me not working any ideas and there is no possibility for entering 00 to one variable it shows error

[jayantverma]

how just you add that three buttons so fastly ? what you use there ?

[keyvaniscool]

I am getting that "(startTimer)" is not defined...

[yadnyeshrane]

Can u give me the link of the image from where i can download the image

[parthverma]

i have written code correctly in all three files...can anyone help me by telling what can be the reason for time not running

[alexhair]

god, this is really a version of the stopwatch code that can be normally modified to work as a timer, I'm damn grateful to you, but I'm still running into problems with manually setting the date via select in html, I hope the option to set the time via input will work.

[Rana]

This is the most easiest way to do that
