• javascript, I'm assuming? What makes you think you can simply stuff a JS OBJECT into a string that happens to contain an html input definition? – Marc B Commented May 23, 2013 at 16:10
• what is a proper way to do it? That an easy way to convert an object to string, will automatically call toString() for that particular object. – Emmanuel N Commented May 23, 2013 at 16:14
• yes, but how is the JS engine to know how to format that stringified date? yyyy-mm-dd? dd-mm-yy? unix timestamp? read up on the JS Date object ... – Marc B Commented May 23, 2013 at 16:15

Use the valueAsDate attribute to convert between a Date object and an input element’s value.

> var elem = document.createElement('input');
> elem.type = 'time';
> elem.valueAsDate = new Date(1970, 1, 1, 7, 34);
> elem.value
"12:34"
