Millisecond Clock

Millisecond Clock shows the exact time down to 1/1000 of a second, accurate enough to measure real delay in cameras, video streams, and network connections.
Point a camera at the screen and compare it to another display: the difference in milliseconds tells you exactly how much latency you are dealing with.

Beyond precision, Millisecond Clock is a clock you can make your own. Every part of it, from color and font to position on screen, is yours to design.
