I have friend who worked on the PRS92 project several years ago.  According
to him, there is very little difference between Luzon Datium and PRS92
datum.  For our intents and purposes on OSM and waypointsdotph, the
difference would be negligible.

What I did then to convert data that is coming in as PRS92, I input those
coordinates into GPSU as Luzon datum then I simply switch over to WGS84 and
GPSU recalculates the new coordinates for WGS84.
