Build ID: 20130511120803

Steps to reproduce:

Using below html code yields a requester in android to pick a time:

<form action="demo_form.asp">
  Select your time: <input type="time" name="time"><br>
  <input type="submit">

When time is set between 00:00 and 00:59, the android requester returns an empty string, ie the field in which you want to place 00:00 is empty. When you input 01:00 the field will get the correct '01:00' value.

The same code is used in Chrome and the return value is as expected, a value between '00:00' and '00:59' instead of '' (empty string) which is the result in firefox for android. 

Actual results:

An empty string is returned in the field.

Expected results:

The string should've been anything between 00:00 and 00:59 as set by the user.

This might very likely be an Android widget issue according to comment 0. If setting "00:00" in the UI sets input.value to "", the DOM code can't do much against that. We should fix our widget implementation to not set the value to the empty string.

Attached patch PatchSplinter Review
Android is returning a real string here. The problem seems to be that our date parsing expects hours in the range of 0-23:

and we're returning a date formatted with kk:mm, which is 1-24 hour time.

This seems like a nice simple fix for Aurora at least, maybe Beta?
