	[[:wikipedia:Network_Time_Protocol\|NTP]] stands for a Network Time Protocol and it is used for keeping device's clock 100% correct by connecting to the NTP servers when needed and getting the accurate time. There is a similar feature in [[Nokia N900\|N900's]] Settings -> Date and time -> Update automatically, but it is for updating the time via mobile network. Keeping the time correct with NTP is better solution, because it is not dependent on mobile network, more common and standard, and you have control over it.

There is a NTP client in extras-testing, [http://www.openntpd.org/ OpenNTPD]. It is widespread Unix/Linux/BSD daemon, which calculates your clock's drift and therefore connects when it is needed, not by schedule. So, enable extras-testing and install package OpenNTPD.

The example configuration file uses European NTP servers. The list by continents and countries is on [http://www.pool.ntp.org/zone/@ ntp.org].
