Check any website’s server time

What is server time?

Every website runs on a server with its own clock. When a ticket sale, sneaker drop or registration “opens at 10:00:00”, it opens by that server’s clock, not by your phone. Server clocks are often off by a fraction of a second, and sometimes by more than a second.

What we’ve measured

• One university’s server clock drifted about 2 seconds a day, and once jumped 0.676 s in a single step.
• One ticket resale site runs several servers, and their clocks disagreed by up to 0.7 s.

How to use

1. Type the site’s address (for example www.axs.com) and press Check.
2. In about 15 seconds we measure how far that site’s clock is from standard (atomic) time, to the millisecond.
3. Set the opening time. The big clock shows the site’s own time, so just click the moment it reaches :00.000.
4. Add it to your calendar or share the link so your friends use the same clock.

FAQ

How accurate is it?

Usually within ±20 ms. Every reading shows its own margin.

Why not just use my phone’s clock?

Your phone can be off too, and it can’t know the site’s clock. We correct for both.

Is this a bot or auto-clicker?

No. We only show the time. You click yourself.
