## What is Millisecond Clock?

Millisecond Clock brings ultra-precise timekeeping to the big screen. Displaying the exact time down to 1/1000 of a second, it is accurate enough to measure real latency in cameras, video streams, broadcasting setups, and network connections.

Point a camera at your TV and compare it to another display or live feed: the difference in milliseconds tells you exactly how much display lag or transmission delay you are dealing with. Beyond testing, it serves as a stunning, retro-modern digital clock for your living room, studio, or workspace.

DESIGNED FOR THE BIG SCREEN
- 29 built-in color themes, featuring deep blacks and crisp whites paired with vibrant fluorescent accents (green, blue, cyan, red, and yellow)
- Authentic 7-segment digital LED typography, crafted for crystal-clear visibility from across the room
- Realistic LED text background: toggle unlit digital segments on or off for an authentic scoreboard aesthetic
- Glowing text effect for a radiant neon look and visual depth
- Seamless Apple TV Remote navigation with fluid tvOS focus effects

STAY ON TIME, YOUR WAY
- 12-hour or 24-hour time formats
- 9 customizable date formats to match how you write dates
- Show or hide the date display with a single click
- Pure, distraction-free full-screen clock experience designed specifically for Apple TV
