Meridian is the super clock for your Mac. Meridian starts with an improved Menu Bar Clock, and adds Alarms, Time Zones, Timers, Stopwatches, and Chimes. Meridian can use its built-in alarm sounds, or use iTunes playlists. Meridian can show you the time in any city, remind you when it's time for an important meeting, track a parking meter, and time a test at school.
