此命令的语法是:


NET TIME
[\\computername | /DOMAIN[:domainname] | /RTSDOMAIN[:domainname]] [/SET]
         [\\computername] /QUERYSNTP
         [\\computername] /SETSNTP[:ntp server list]


C:\Documents and Settings\Administrator>net time \\127.0.0.1
\\127.0.0.1 的当前时间是 2012/9/18 下午 02:41

命令成功完成。

### Singapore NTP Pool Server Configuration and Information The Singapore NTP pool server is part of the global NTP pool project, which provides reliable and accurate time synchronization services. The domain `sg.pool.ntp.org` represents a set of NTP servers located in Singapore. These servers are managed by volunteers and organizations that contribute to the NTP pool project. For Singapore, the following NTP servers are available: - **sgp.ntp.org.cn** This is a specific NTP server for Singapore under the `ntp.org.cn` domain[^1]. It includes the following IP addresses: - 139.162.20.174 - 103.11.143.248 To configure an NTP client (e.g., using `chrony` or `ntpd`) to synchronize with the Singapore NTP pool, follow these steps: 1. **Edit the NTP Configuration File** For `chrony`, edit the configuration file `/etc/chrony/chrony.conf` or `/etc/chrony.conf`. Replace or add the following line to specify the Singapore NTP pool server: ```bash server sg.pool.ntp.org iburst ``` 2. **Restart the Chrony Service** After modifying the configuration file, restart the `chronyd` service to apply the changes: ```bash systemctl restart chronyd.service ``` 3. **Enable and Start the Service** Ensure that the `chronyd` service starts automatically at boot and is currently running: ```bash systemctl enable chronyd.service systemctl start chronyd.service ``` 4. **Verify the Configuration** Use the `chronyc` command to check the status of the NTP sources: ```bash chronyc sources ``` This command will display the list of NTP servers being used and their synchronization status. Additionally, if you prefer to use a specific server instead of the pool, you can replace `sg.pool.ntp.org` with one of the IP addresses listed under `sgp.ntp.org.cn`[^1]. ### Example Configuration for Chrony Below is an example of how the `chrony.conf` file might look when configured to use the Singapore NTP pool: ```bash # Use public servers from the pool.ntp.org project. # Please consider joining the pool (http://www.pool.ntp.org/join.html). server sg.pool.ntp.org iburst # Local clock source (optional) local stratum 10 # Drift file driftfile /var/lib/chrony/drift # Allow NTP client access from localhost allow 127.0.0.1 ``` This configuration ensures that your system synchronizes time accurately with the Singapore NTP pool servers. ---
