Are people who go in to work early (thus leaving earlier) appreciated less than those who work late?

I am a morning person. Because of this, I find that getting in to the office at 6 AM works really well for me because not only is no one there at that time, but I can leave at 5 PM and still have a night to look forward to at home. On the other hand, there are people who come into the office at 10 or even 11 AM, and work until 9 or 10 at night. These are the people who always get the accolades by our superiors. I get the “look” when I pack up my things at 5, despite the fact that my 11 hour day is at an end.

Anyone have any opinions on this?

This, of course, only applies to those who work in places where there is no set “start” time.
