There's clocks and there's clocks and then there's UTC Global Clock. UTC Global Clock is quite possibly the most complicated and detailed clock for Mac I've ever used and this presents both good and bad things.
On the plus side, you can do a whole host of organizational tasks through UTC Global Clock. On the negative side, it's ridiculously complex and detailed and takes ages to understand all of it's functions. UTC Global Clock features a whole host of time-related functions, including time displays, hourly chimes, timers, stopwatches, calendars, and much more.
At it's most basic, UTC Global Clock will display and any world time zone in a corner of your screen. At it's most advanced, it can do everything from remind you to walk the dog to setting a stopwatch to record how much time you are working on a project. On a functional level though, it can be rather annoying. For example, as you go to wave your mouse over the time on the corner of your screen, it simply disappears for some strange reason. To access all of it's functions, you must go to your top menu bar where clicking on the time will reveal a drop down menu with a host of options from adding calendar reminders to configuring keyboard shortcuts.
Overall, I wasn't really blown away by UTC Global Clock despite it's obvious depth. There are plenty more elegant world time clocks for Mac, and anything that requires a calendar I'd use iCal or Google Calendar for anyway, although if you don't use any kind of organizer, you may find the extra functions useful.
UTC Global Clock wins full marks for depth and features although it's presentation and functionality let it down.
