In google chrome if I set the value of an input of type datetime-local to a time containing seconds where the seconds value is 0 Chrome decides not to show the seconds value on the input, meaning the user can't set the seconds at all.
E.g. If I set the value to 2013-10-24T20:36:01 then Chrome will show an input and the user can change the day, month, year, hours, minutes and seconds to whatever they want (including 0). If I set the value to 2013-10-24T20:36:00 then the seconds part disappears. I can understand it not being shown if no value for seconds was passed in but I am explicitly setting them to 0 so I would have assumed it would show them.
The reason why this is a problem is because I am reading the times from a database and if any of them have been set to 0 seconds the user can't change the time without hacking it with developer tools!
Am I missing something?
Thanks!
Adding step attribute will resolve your issue.
<input type=datetime-local value="2013-10-24T20:36:00" step="1">
The default value of step attribute is 60 (one minute).
