System Basics Introduction

System Time

Routers are equipped with a real-time system clock for time keeping purposes. When set, the
system clock always operates on Coordinated Universal Time (UTC), but the software has options
for local time translation as well as system clock synchronization.
System time parameters include:
•
•
•

Time Zones

Setting a time zone in allows for times to be displayed in the local time rather than in UTC. The
has both user-defined and system defined time zones.
A user-defined time zone has a user assigned name of up to four printable ASCII characters in
length and unique from the system-defined time zones. For user-defined time zones, the offset
from UTC is configured as well as any summer time adjustment for the time zone.
The system-defined time zones are listed in
without summer time correction.
