As I understand it, there is no practical difference between -tsset- and -xtset- currently. (If that turns out to be incorrect, I'm sure someone else will pipe in.) -xtset- was introduced in an update to Stata 9, hence it is not in your [XT] manual if it's an early printing. -help xtset- will provide more information. Search -help whatsnew- for -xtset- to can learn a little about the story behind its introduction.

Hope this helps.
