I guess it keeps the EU-style time change; as the "hora oficial" is the time used in mainland (Chile Continental). Easter Island is called "Hora Oficial de Chile Insular Occidental", as per decree 1142-1980 from Ministerio del Interior <http://www.leychile.cl/Navegar?idNorma=17012>.
Perhaps you're right; still, it is odd. The decree does not mention anything like an EU-style practice; it talks only about a transition at 24:00, regardless of location. On the other hand, the 2008 announcement from SHOA (Servicio Hidrográfico y Oceanográfico de la Armada de Chile) looks official too and is quite explicit using an EU-style practice. Possibly SHOA is entrusted with determining what "24:00" means, and has decided that it means 24:00 at SHOA headquarters rather than 24:00 local time. If so, we should revert that part of the Chile change (i.e., revert the user-visible aspect of commit 483247fc9b735097ff2c06531204913317a5056c). It would be nice to have some confirmation of this, though. One possibility is to wait until SHOA announces the change on their website. (It's not there yet.)
