As a first step, the wizard will make two suggestions as to the internal time configuration.
Click on the "Modify" icon of what you want to setup:
Time zone and NTP server address: to indicate the physical location of the
server, and eventually set up a time server which would automatically set
the system's date and time.
Date and time: if you have no NTP server, click on the "Modify" button to manually set the current date and time on the machine.
