Official Atomic Standard Time & Device Clock Calibration
Official Standard Time is maintained by national metrology institutes and distributed globally via stratum-1 Network Time Protocol (NTP) atomic clock servers. TrueTime synchronizes your browser session against our reference server clock, compensating for network transit delay.
You can use this page to verify whether your computer or smartphone clock is running fast or slow and calibrate your system time to match official standard time down to the millisecond.
Key Features & Usage Guide
- Instant verification of your device clock accuracy against synchronized standard time
- High-precision millisecond readout for exact visual clock calibration
