Time Server IP address and time synchronization method of China National Time Service Center

Time Server IP address and time synchronization method of China National Time Service Center

 

We all know that the computer's time is maintained by a battery power supply, and the accuracy is poor, often when you are inaccurate. Some public network time servers published on the InternetNTP server, you can automatically and periodically synchronize the standard time of the local machine.

Rely onBy default, windows, NIST, and other overseas time server synchronization time are affected by access congestion, large time delay (low synchronization accuracy), and other factors. Now, China's national time service center has released a time server address. You can use your own standard time!

Method 1The time synchronization feature provided by windows, Linux, and other operating systems is used.

ForWindows 2000 and XP have integrated the automatic time pair function.ArticleMany operations are introduced. Here we will introduce the XP operating system as an example.

Double-click the time below the system tray.In the date and time Properties dialog box, select the Internet time tab. In the server address bar, enter the IP address of the National Time Service Center Server (210.72.145.44), and click "OK" to save it. You can select automatic synchronization or manually press "Update Now" to synchronize the time.

Method 2. Modify the Registry to improve time synchronization accuracy

The default time synchronization interval isIn seven days, we were unable to choose freely, which greatly reduced the flexibility of this function. In fact, we can also manually modify its automatic synchronization interval by modifying the Registry to improve synchronization accuracy. The following uses the XP system as an example.

1. Enter "start"> "run"Regedit

2. Expand[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ w32time \ timeproviders \ ntpclient] branch, double-click the specialpollinterval key value, and select "base bar" in the dialog box to "decimal"

3. The number displayed in the dialog box is the time interval for automatic matching.(In seconds). For example, the default 604800 value is calculated by 7 (days) × 24 (hours) × 60 (minutes) × 60 (seconds. Set the time synchronization period (recommended to set to 900 = 15 minutes or 3600 = 1 hour), fill in the dialog box, and click OK to save the close dialog box.

4. InIn the parameters list, change the ntpserver key value to the IP address of the National Time Service Center Server (210.72.145.44), and click "OK" to save the modification.
