Please select a time zone location by line number:(1-30) 11
In this example Chicago is selected. By requesting CLI help on the command you can see how to configure the time
offset using Greenwich Mean Time:
configure clock timezone ?
WORD country name/zone location e.g. America/Chicago, or GMT offset e.g. GMT-6 <cr>
Use the following command to set the time zone offset in hours (and minutes, if applicable) from Greenwich:
configure clock timezone GMT[+|-hh[:mm]]
Use the no form of the command to disable the time zone setting:
configure clock [no] timezone
Use the following command to display clock configurations and the time:
show clock detail
2012 February 4 09:53:39 CDT (DST)
Network time sync protocol is TOD
TOD Server IP Address: 10.50.28.3 connection type: tcp
These commands select the local TZ and DST rules based on canonical <TZ name> or GMT offset. The TZ and DST
adjustments are made automatically whenever the local time is displayed or logged (see show clock detail or show log
history command).
When a canonical <TZ name> is given, the built-in local TZ and Daylight Saving Time (DST) rules for that time zone
location name are activated. This includes automatic adjustment of local time for TZ & DST and setting of the time zone
abbreviation according to the rules. Examples of canonical TZ names are Europe/Paris, America/Chicago, or
Asia/Hong_Kong.
When a GMT offset is given, the local TZ is set accordingly, but no DST adjustments are made when local time is
displayed or logged.
