UTC Scroll for Mac

UTC Scroll allows you to browse through dates and times with nanosecond-accuracy and correct support for UTC with leap seconds, including time shifts.

Simply scroll through days, months, years, centuries or change the clock by dragging the desired field with your mouse or using the scroll gesture when hovering over it. Alternatively, you can enter the dates manually. You can also change the speed of the clock arbitrarily from seconds up to thousands of years both positive and negative with a slider or a simple menu command.
