TimeTicker shows the exact atomic time in cities and countries in all time zones, automatically adjusted for local Daylight Saving Time rules. TimeTicker is synchronized with the NIST-Server. Even if your iPhone or iPod has different time, the time shown in TimeTicker-App is correct by the second.
On the settings pane you can insert, reorder and add cities or locations. Additionaly you have the option to switch off TimeTicker's ticking and to select between am/pm and 24h display. Have fun!
