From the developer:
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 speed of the clock arbitrarily from seconds up to thousands of years both positive and negative with a slider or a simple menu command.
You may want to check out more software for Mac, such as Volume-Scroll, UTC Clock or UTC Bar, which might be similar to UTC Scroll.
