# NTP
|
|
|
|
[NTP](https://www.rfc-editor.org/rfc/rfc5905) - short for Network Time Protocol
|
|
- is the most common method to synchronize the software clock of a
|
|
[Linux](/wiki/linux.md) system.
|
|
|
|
## Setup
|
|
|
|
NTP can be installed on most distributions by installing the
|
|
`ntp` package.
|
|
|
|
## Usage
|
|
|
|
The following section describes the usage of the NTP package.
|
|
|
|
### Synchronize Time once
|
|
|
|
For one time synchronization of the time and date the `ntpdate` command can be
|
|
used.
|
|
The following command is an example for a one time sync.
|
|
Note that the server has to be changed for different time zones.
|
|
In this case a german time server is used.
|
|
|
|
```sh
|
|
ntpdate ptbtime1.ptb.de
|
|
```
|
|
|
|
Alternatively the time can be displayed only - without changing the systems
|
|
time - by using the `-q` flag.
|
|
|
|
```sh
|
|
ntpdate -q ptbtime1.ptb.de
|
|
```
