That won't be entirely accurate. The attribute is described here:

And discussed here:

Which tells us that the attribute above may be off by as much as 14 days.

So it's great, depending on how accurate you need / want to be.

Is there a way to see the history over a period of time rather than just the last logon stamp?

Nope, both lastLogon and lastLogonTimeStamp are single value attributes.

Basically, if you want a history you'd have to write something to maintain it, perhaps something through a logon script?

It would be possible to do it on the server side, but for accuracy you'll need the lastLogon attribute. The problem is, that one isn't replicated, which means you have to check every DC in your environment to get the actual value. That would be painful if it were required of a regular basis.
