Datebar remember some previous history

[Puckfist]

While investigating a server crash I was looking at a very specific period of time. I then wanted to compare it to a larger period of the server's behavior. and then I found myself wanting to return to the time of the incident for that point or others.

I think it may be a good feature to give the date bar a memory of times, perhaps the last 10 the user selected or whatever.
