And you want to return just one, right? What about:

  data[@id = 'archive']/timestamp[@time < 1099119599][last()]

Depending on your XML structure -- if the <timestamp> elements that
you're interested in might appear within different <data> elements --
you might need to use brackets as in:

  (data[@id = 'archive']/timestamp[@time < 1099119599])[last()]

Cheers,
