First of all, the wizard will make two suggestions as to the
internal time configuration.
Click on Modify icon () relative to what
you want to setup:
Date and Time: if you do not have a NTP server, click on the
Modify button under the Time 24-hour (hh:mm:ss) field to manually
set the current date and time on the machine.
Time Zone and NTP Server Address: click on the Modify button
under the NTP Server Address (optional) field 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.
