- Setting the server time - Remember to set the server date correctly according to the time zone of which the main part of the users of the system are located. This will affect e.g. when scheduled tasks are executed. For instance, to the set time to 22:45, October 17, 2012, invoke sudo date 101722452012. - It may be necessary to reconfigure the time zone of the server to match the time zone of the location which the DHIS2 server will be covering. If you are using a virtual private server, the default time zone may not correspond to the time zone of your DHIS2 location. You can easily reconfigure the time zone by invoking sudo dpkg-reconfigure tzdata and following the instructions. - It is easy to keep your server very accurate by using the NTP package. You can install it by simply invoking sudo apt-get install ntp. NTP will automatically syncronize your server time on a regular basis. + Setting the server time zone + It may be necessary to reconfigure the time zone of the server to match the time zone of + the location which the DHIS2 server will be covering.
