Understanding Server Time Errors
Learn about the causes of time errors during ticketing and course registration
Why do time errors occur?
Server time checking sites send HTTP requests to specific servers and parse the Date information from the response header to estimate the time. In this process, time errors inevitably occur due to various technical factors such as network delay, precision limits, and browser constraints.
Causes of Time Errors
Network Round Trip Time (RTT)
50~300msTime is required for the round trip from client to server and back. It varies depending on physical distance, network congestion, and ISP routing paths.
Date Header Precision Limit
max 999msHTTP Date headers only provide precision up to seconds according to RFC 7231 standard. Without millisecond information, there is up to 999ms of uncertainty.
Date: Sun, 22 Dec 2024 12:00:00 GMT → .000 ~ .999
JavaScript Timer Drift
4~5ms/secsetTimeout/setInterval only executes when the event loop Call Stack is empty. This error accumulates over time.
Browser Background Throttling
CautionWhen browser tab is inactive, timer execution is limited to 1 second+ intervals to save CPU. Chrome applies severe performance limits after about 10 seconds in background.
→ Make sure to keep the tab active just before ticketing
Server Processing Queue Delay
100ms~secWhen traffic spikes right after opening, server processing delay increases dramatically. Additional delays may occur from CDN and load balancers.
