For the US, the tide datum is MLLW. For most of the rest of the world it's LAT. Why doesn't Mr. Tides say what the datum is? Because no-one has asked for it before. I'm currently rewriting Mr. Tides to be Lion-compatible and I can add this in to the information presented. As far as being "useless", well that's your opinion but I view it as hyperbole and tend to ignore it.
