Error Validating Seconds in HTML5 Time Input?

This post is more than 18 months old. Since technology changes to rapidly, this content may be out of date (but that's not always the case). Please remember to verify any technical or programming information with the current release.

Turns out, it’s just another issue of RTFM - but maybe this will save you some headache!

I was using a simple HTML5 input of time…

<input type="time" name="the-time">

At first, the user would enter something like “4:00 PM” - which I’d convert to 15:59:59 on the backend. When I reloaded the page, it now reflected “3:59:59 PM” in the input field.

Then, the user would go to edit the time to say… “3:30:00 PM” and they’d get the following error in Chrome:

“Please enter a valid value. The two nearest valid values are…” - that didn’t make any sense to me.

Well, turns out that every number field in html5 spec is using step=1 on the input fields - however, time is using step=60 - as in 60 seconds. (I guess the authors preferred minutes over seconds). The spec clearly defines this - but I guess I just missed that part.

Hopefully it saves you some time too - in the end, this is what I changed my input field to - and it worked!

<input step="1" type="time" name="the-time">
