The best world clock for Mac with a great design. Add any location, or timezone (i. e. CET, EST) you want - 24-hour and AM/PM styles. Optional time and location name in the menu bar. Optional relative dates (yesterday, today, tomorrow). Possibility to rename cities (so that you can replace it with the name of the person living there). Travel through time using the slider at the bottom of the window, so you can easily figure out the best time to set that meeting with the overseas office. Optimized graphics for Retina displays.
