Note Several more time zones are available to you. On your Cisco CDA server, enter show timezones. A list of all the time zones available in the Cisco CDA server appears. Choose the most appropriate one for your time zone.

Warning Changing the time zone on a Cisco CDA appliance after installation causes the Cisco CDA application on that node to be unusable. However, the preferred time zone (default UTC) can be configured during the installation when the initial setup wizard prompts you for the time zone.

Examples

/admin(config)# clock timezone EST
