Time & Productivity

Accurate Taiwan Standard Time clock with NTP synchronization, and a multi-mode stopwatch with lap timing, record tracking, and speedcubing support.

Effective time management starts with the right tools. Whether you need precise timekeeping for exam proctoring, lap timing for athletic training, or millisecond-accurate timing for speedcubing, our time tools deliver accuracy and reliability — all from your browser.

Online Stopwatch

Free online stopwatch with 4 modes: Simple mode (start/pause/quick restart), Record mode (top 3 best times), Loop mode (lap timing with fastest/slowest marks), Cube mode (hold-release start like csTimer). Fullscreen, millisecond precision, keyboard shortcuts. Ideal for running, cooking, lab work, and speedcubing.

Time & Date

Taiwan Online Clock

Get the exact current local time in Taiwan (TST/UTC+8) with millisecond precision. Features a fullscreen mode for events and exam proctoring. No DST adjustment needed.

Time & Date

The Taiwan Clock provides an accurate UTC+8 time display with dual-API NTP synchronization. It automatically fetches the current time from timeapi.io and worldtimeapi.org, calculates your device's time offset, and applies corrections in real-time. Re-synchronization occurs every 5 minutes to prevent drift. Full-screen mode makes it ideal for exam halls, New Year countdowns, and conference room displays.

The Stopwatch offers four distinct timing modes. Simple Mode for quick start/stop timing. Record Mode automatically tracks your best 3 results with ranking badges. Loop Mode supports lap timing with automatic fastest/slowest lap marking. Cube Mode uses a press-and-release mechanism for zero-delay starting, perfect for speedcubing. Keyboard shortcuts (Space, L, C, F) and millisecond precision make it suitable for sports, laboratory work, and cooking.

Frequently Asked Questions

Which is more accurate — Taiwan Clock or my phone clock? ▼

Both are comparable, but our clock adds an extra layer of accuracy through dual-API NTP cross-verification. It can detect and correct minor system time offsets that your phone might miss.

Can I use the stopwatch offline? ▼

Yes. All stopwatch logic runs client-side using the performance.now() API. Once the page loads, it works without an internet connection. For extended sessions (several hours), restart periodically to minimize browser-induced drift.

How does the Cube Mode touch start work? ▼

Cube Mode uses a press-and-release mechanism: hold the button to arm it, release to start timing instantly. This eliminates the 0.1-0.3 second delay inherent in traditional button presses, ensuring the timer starts the exact moment your fingers leave the button.
