World Clocks displays time in 12 different time zones around the world. More than 400 towns in the world along with the accurate DST rules applied are available for your clock selection. If you do not find your town in the list, you can select a nearby town and assign your own customized name to the clock.

For all cities the accurate DST (Day Light Saving) rules are maintained for this year and for several more years to come. All clocks are thoroughly tested for DST rules at various cities. For example, Karachi (Pakistan) applied DST in 2009, but does not apply DST in 2010 and all future years through 2019. All such rules are carefully coded and tested. Observing a DST rule, a clock will advance or decline automatically at the DST transition. Thus, NO TIME ADJUSTMENTS ARE REQUIRED EVER ON ANY OF THE CLOCKS.
