This operation guide describes how to configure DNS without using DST.
Conditions
Log in to the server as user root through telnet mode.
The change of the DNS server time zone results in the change of time at the Solaris bottom layer. In this case, all the timers depending on the operating system are reset or become invalid. To avoid the function failure caused by invalid timers, you need to stop the DNS services before you change the server time zone. During this period, the performance data and alarm data of the managed NEs cannot be handled in time. After the DNS services are restored, the DNS services starts the automatic synchronization function, and collects and handles the missing performance data and alarm data from the managed NEs.
If you need to change both the time and the time zone, change the time zone first.
Procedure
Run the following command to change the value of TZ in the /etc/TIMEZONE file to the name of the required local time zone.
In this case, GMT+N indicates that the local time is N hours later than the GMT. GMT-N indicates that the local time is N hours earlier than the GMT. Before the change, ensure that the binary time zone file corresponding to the GMT time zone exists in the /usr/share/lib/zoneinfo directory. Otherwise, the change fails.
The /etc/TIMEZONE file is read-only. Save the file after modification.
