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>.

Probably Eduardo could ask around and check that.
