Diagnóstico de hora del dispositivo
Prueba de deriva del reloj
Compare your device clock with network-calibrated atomic time. Use the offset, delay, and accuracy estimate to decide whether your computer needs a time sync check.

FAQ de deriva
What is clock drift?
Clock drift is the difference between your device clock and a more reliable time reference.
What offset is acceptable?
A few hundred milliseconds is usually fine for browsing, while authentication and distributed systems often need tighter alignment.
How does this test estimate accuracy?
Time.ms measures network round-trip delay and uses half that delay plus a small browser timing allowance.
