Some sources say Guatemala will observe DST this year. For instance Steffen Thorsen: http://www.timeanddate.com/worldclock/city.html?n=94 DST starts on Sunday, April 30, 2006 at 12:00 Midnight local standard time DST ends on Sunday, October 1, 2006 at 12:00 Midnight local daylight time TZ database still has no DST since 1991. What is the truth?
