Server Time - Ticket Time

Ticket Time shows a booking site's server clock down to the millisecond and automatically refreshes your browser when the on-sale time arrives.

■ Why server time
A ticket drop opens on the booking site's server clock, not on your phone's — and server clocks disagree. In our measurements Interpark ran 200 ms behind and YES24 500 ms behind. Tap by your phone clock and you are already late.

■ Features
· Live server time of your chosen site, to the millisecond
· The error margin (±ms) is always shown next to the clock, so you know how far to trust it
· Floating clock over your booking page (drag to move, adjustable transparency)
· Auto-refresh the browser at a set time (e.g. right at open)
· Lead-time compensation in milliseconds for the delay before the refresh actually goes out
· Countdown beeps through the last 10 seconds
· Repeat refresh at the interval you choose
· Presets for ticketing, restaurant, campsite and train booking sites + add any site you want
· 347 Korean university course-registration servers built in — search by name
· Supports Chrome, Samsung Internet, Whale, Edge, and Brave
· Community: chat live with people waiting on the same site

■ Use cases
· Waiting for concert, musical, or sports ticket drops
· University course registration on the school's own server clock
· Holiday train tickets (SRT, KTX)
· Campsite, accommodation, or restaurant booking that opens at a set time
· Any page that opens right on the clock

■ How server time is measured
Instead of your device clock, the app probes the site's server responses several times and shows a calibrated, server-based time. Servers only report whole seconds, so the app probes densely just before the server's second rolls over and narrows the range across samples to get milliseconds. The method and the error margin are shown, not hidden.

This app uses the Accessibility Service to detect the foreground browser and tap its refresh button. It does not read, collect, or transmit your screen content — it is used only to perform the refresh.
