Big Window Clock at Mac App Store analyse

Big Window Clock shows the current time, in your Macs time zone, in the largest possible font for its window. Optionally, it makes a "tick" sound periodically. Use Big Window Clock to measure audio/video sync drift, where your audio and video capture devices dont run at precisely the same speed. Point your camera at the screen, enable the periodic "tick", and check your sync drift after an hour or so. Or use Big Window Clock when you need a really big digital clock that you can read from across the room. Its as simple as I can make it: no messing with font, or colors, or low level configuration.
