## Usage<a name="section121401651173816"></a>

Run the  **ntpdate **\[_SERVER\_IP1_\] \[_SERVER\_IP2_\]... command.  **ntpdate**  obtains and displays the time of the first server with a valid IP address.

## Example<a name="section3431554203811"></a>

Run  **ntpdate 192.168.1.3 **to update the system time.

## Output<a name="section18638194610115"></a>

```
OHOS # ntpdate 192.168.1.3
time server 192.168.1.3: Mon Jun 13 09:24:25 2016
```

If the time zone of the board is different from that of the server, the displayed time may be several hours different from the obtained server time.
