Daylight-saving time information for Chile and Guatemala has been updated. Chile decided to extend daylight-saving time this year from the second to the last Saturday in March as part of a series of measures to address the energy problems caused by a monthslong drought. Guatemala is reintroducing daylight-saving time in 2008 and will observe it from the last Sunday in April to the last Sunday in September.
San Luis, Argentina has been added to the World Clock Deluxe cities database. After Argentina moved to daylight-saving time on December 30, 2007, the San Luis province decided to return to standard time on January 21, 2008 much earlier than the rest of the country.
