The heart of the time service is the system clock. This clock runs from the moment the system starts up
and keeps track of the date and time.
The system clock can then be set from these sources:

The system clock can provide time to these services:

•
The system clock determines time internally based on Universal Time Coordinated (UTC), also known
as Greenwich Mean Time (GMT). You can configure information about the local time zone and summer
time (daylight saving time) so that the time is correctly displayed for the local time zone.
The system clock keeps track of whether the time is authoritative or not (that is, whether it has been set
by a time source considered to be authoritative). If it is not authoritative, the time is available only for
display purposes and is not redistributed. For configuration information, see the
