You can use the STATS_DATE function to determine the last time the statistics were updated.
You should also check out sp_updatestats. The benefit of it, starting with 2005, is that it determines which statistics need updating. If any stats are up to date, then it won't update them. For this reason, we don't even bother checking if stats are out of date. We just run sp_updatestats.

There's a new post coming up on my blog on Friday that's an introduction to statistics as part of SQL University's Index Week. Keep an eye out for it. It might help explain a few things. Gail has a great post on them available now[/url].
