Server (Calibrated) Clock
Servers like this one talk to other servers all over the
globe some
even engage in business and other things where accurate time is
essential. This accurate clock is achieved through the UTC (Universal
Time Clock) set
to Time Zone 0 or Greenwich Mean Time. GMT and UTC are not mindful of
Daylight Savings Time (DST) and therefore are not affected by changings
to DST in your area. In order to ensure every server's clock has the
same time the server clock is periodicaly calibrated with an external
clock known as an Atomic Clock through NTP (Network Time Protocol) and
this clock here shows that time.
