Beijing Time

Tool Guide

Tool Overview

The Online Beijing Time Calibration Tool uses the standard Beijing time from the National Time Service Center displayed on this page to calibrate your local device time, letting you understand the error range between your device time and the standard time.

This site's server automatically syncs with the National Time Service Center's standard clock every 5 minutes to ensure the server time stays consistent with the National Time Service Center time.

Because server processing and network requests both have varying degrees of latency, the displayed time and the standard time may have an error of about 20-50 milliseconds; you can refresh the page multiple times and take the average.

The National Time Service Center's new NTP server address is: ntp.ntsc.ac.cn. You can set your device's network time server yourself to sync and calibrate your device time.

You can also use our timestamp API to sync time: https://api.shijian.online/timestamp/.
