1. UTC = universal time coordinated
The minutes-offset variable in the clock timezone command in global configuration mode is available
for situations where a local time zone is a percentage of an hour different from UTC. For example, the
time zone for some sections of Atlantic Canada (AST) is UTC-3.5, where the 3 means 3 hours, and the
.5 means 50 percent. In this case, the necessary command is clock timezone AST -3 30.
To set the time to UTC, use the no clock timezone command in global configuration mode.

Configuring Summer Time (Daylight Saving Time)

To configure summer time (daylight saving time) in areas where it starts and ends on a particular day of
the week each year, follow these steps, beginning in privileged EXEC mode.
