If you use Spaces, you can now have the Clocks palette always available, no matter which space you're in, by selecting the "Show palette in all spaces" checkbox in the Palette pane of World Clock Deluxe Preferences.
Daylight-saving time information for Bangladesh, Egypt, Israel, Morocco, and Western Sahara has been updated. This year, Bangladesh will observe DST from March 31 to November 1, while in Israel DST will start on March 26 and end on September 12. Egypt, Morocco, and Western Sahara may not observe daylight-saving time in 2010.
10 cities on the Northern Mexican border will soon adopt the same daylight-saving time rule as the United States (second Sunday in March to first Sunday in November). Daylight-saving time information has therefore been updated for Tijuana and Mexicali in the state of Baja California, and the remaining 8 border cities have been added to the World Clock Deluxe database. New cities are:
| Chihuahua | Ciudad Juárez, Ojinaga |
| Coahuila | Ciudad Acuña, Piedras Negras |
| Nuevo León | Anáhuac |
| Tamaulipas | Nuevo Laredo, Reynosa, Matamoros |
Some other minor improvements have been introduced.
