Limit widget hours: setting not saving

Indeed, in the settings form the start hours are not saved correctly, and have the same value as the end hours.

Updating title. More issues report having problems with this field.

Any updates on this bug?

Can't find the cause of this weird problem. Any patches are welcome.

For some reason we've used 'office_hours_select' as an element, but it doesn't really make sense because limiting hours concerns hours and not minutes and you can't decide which time format to use - so I've reverted to using a simple select box and using both.

A patch is supplied, please test, seems to work for me.

This is a very nice piece of work! Enabling the not-allowed hours is a good thing.
It has one drawback, a per the next example:
- edit a node, set the hours to 9-17
- set the allowed values to 10-18
- edit the node again, the invalid hours are now empty, without showing a warning.

I could not apply your patch. Then I noticed that it was already committed to 6.x-1.x, so I am correcting the status.

And attached patch corrects some trailing spaces and code styling (no return + break).

Also committed.
