No Alarm SetBase: true-time.hongry.dev Server Time
Please set a target time or timer preset.
The alarm will trigger based on the precise target server (true-time.hongry.dev) when the duration expires.
※ Triggers an alarm in 10 seconds to verify audio and push notification execution in background/locked states.
How Real-Time Server Time Synchronization Works
TrueTime measures the exact clock of any target web server by inspecting real-time HTTP response timestamps and compensating for network Round-Trip Time (RTT) down to the millisecond (ms).
Even modern operating systems experience clock drift of several hundred milliseconds between background NTP updates. When competing for time-sensitive events that open at the exact top of the minute (:00.000), relying on the remote server clock rather than your local device clock is essential.
Key Features & Usage Guide
- Instant server clock lookup for any domain with live RTT latency compensation
- Side-by-side comparison between your device local time and the target server time
- Built-in 10-second early warning chime and exact target-time alarm notifications
Frequently Asked Questions (FAQ)
- Q. Why does my device clock differ from a website server time?
- Local devices only synchronize with internet time servers periodically, causing gradual hardware clock drift. Web servers maintain their own NTP synchronization pools, resulting in measurable offsets between your browser and the target server.
- Q. What does Round Trip Delay (RTT) mean?
- RTT is the time in milliseconds required for a network packet to travel to the server and return. TrueTime factors in RTT to estimate the true instantaneous time on the remote server.
