This is a simple, easy-to-use, autonomous clock. What makes the clock autonomous is that you never need to set the time - you simply turn it on and it displays the current time using signals received from global navigation satellite system (GNSS) satellites that are orbiting the earth. 

UTC Time:

Coordinated Universal Time (UTC time) is displayed in 24-hour format by default on the clock. Devices can be built with custom time zone and/or daylight savings time settings depending on preferences.

Uninterrupted Power:

The clock contains an internal rechargeable battery so that it can operate for extended periods if the external power goes out. The clock can be made with a Blue, Red, or Green digital LED matrix display.

Uses: 

This clock is suitable in environments where accurate, always-reliable time is essential—even during power interruptions—and where manual time-setting would be impractical or error-prone. Ideal placements include:

• Scientific and calibration laboratories — Provides a UTC reference for experiments, equipment synchronization, data logging, and metrology work, ensuring measurements remain accurate and compliant.
• Manufacturing facilities and factories — Assists coordination in production lines, shift scheduling, machine timing, quality control processes, and Industry 4.0 automation systems that require sub-second (or better) synchronization across devices.
• Industrial workspaces and control rooms — Offers a clear display for operators, technicians, and teams needing a shared, GNSS-derived time source that holds accurate time during outages.
• Server rooms and data centers — Serves as a visible reference clock alongside networked timing systems, helping with troubleshooting, logging, and operational continuity when GNSS signals are available.
• Test and measurement setups — Useful in engineering bays, R&D areas, or field testing stations for timestamping events, correlating data from multiple instruments, or validating timing in systems.

In any of these settings, the clock's set-it-and-forget-it autonomy, combined with battery backup, eliminates drift concerns and supports workflows that demand high time precision and resilience.
