Managing the System Time and Date
The
minutes-offset
variable in the
clock timezone
global configuration command is available for those
cases 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 .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
global configuration command.
Configuring Summer Time (Daylight Saving Time)
Beginning in privileged EXEC mode, follow these steps to configure summer time (daylight saving time)

For
hours-offset
