Exact Time · Server Clock.
Exact Time Now
The current UTC time as reported by our server, with an estimate of how far your device clock has drifted from it. Good for everyday device-clock comparison — not a certified atomic-clock-grade reference.

DRIFT
Why Clocks Drift
Device clocks count time with a quartz crystal whose rate varies slightly with temperature and manufacturing tolerance, so a clock that is not corrected gains or loses a little every day. Operating systems correct this by syncing with a time server from time to time; between syncs, and while a laptop is asleep, the error can build up to a few seconds.

FAQ
Frequently Asked Questions
- What is the exact time right now?
- The current UTC time displayed at the top of this page is taken from our server clock. Our server clock is itself kept in sync via the cloud provider's underlying NTP infrastructure (AWS Time Sync), which traces back to public time references. This is good for everyday device-clock comparison; it is not a certified atomic-clock-grade time signal.
- How accurate is this page?
- We measure the offset between your device clock and our server clock by sampling our /api/time endpoint and subtracting half of each round-trip from your clock. The accuracy you get depends on your network jitter and how recently your device last synced. We do not claim a fixed accuracy bound — for legal, contractual, or scientific time-stamping you should use a dedicated time-synchronization service.
- Why is my computer clock wrong?
- Computer clocks use quartz crystal oscillators that drift by several seconds per week due to temperature changes and manufacturing tolerances. While operating systems synchronize periodically via NTP, the interval between syncs (often hours or days) allows drift to accumulate. Laptops in sleep mode can drift even more since sync is paused.
- What is an atomic clock?
- An atomic clock measures time by counting the microwave oscillations of caesium-133 atoms, which vibrate exactly 9,192,631,770 times per second. This frequency defines the SI second. Modern optical lattice clocks using strontium or ytterbium achieve accuracies of 10⁻¹⁸, meaning they would lose less than one second over the age of the universe.
- What is NTP (Network Time Protocol)?
- NTP (RFC 5905) is the standard protocol computers use to synchronize their clocks over a network. It uses a hierarchy of time sources called strata: Stratum 0 are atomic clocks and GPS receivers, Stratum 1 servers connect directly to them, and Stratum 2+ servers cascade from there. NTP can achieve accuracy within a few milliseconds on LANs and tens of milliseconds over the internet.
- What is UTC?
- Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is maintained by the Bureau International des Poids et Mesures (BIPM) using data from over 450 atomic clocks in 80+ laboratories worldwide. UTC is within 0.9 seconds of UT1 (mean solar time) thanks to occasional leap seconds.
