Changing the timezone configuration inside Netezza Performance Server container

Change the system timezone by updating the symbolic link in the /data/localtime directory to point to a timezone file in /data/zoneinfo.

Before you begin

Root or administrative access to the system.

About this task

The system is configured to use UTC as the default timezone when the container is deployed. Customers who require a different timezone must configure it after deployment by following the procedure in this document. Timezone definitions are available under the /data/zoneinfo directory. This directory is created automatically during container deployment and contains the supported timezone definitions. Select the required timezone from this directory when updating the symbolic link

Procedure

From the system console, verify the current timezone setting by running the following commands:
```
ls -l /data/localtime
date
```
The output displays the symbolic link pointing to the current timezone file and the current system date and time.
Remove the existing timezone symbolic link:
```
unlink /data/localtime
```
Create a new symbolic link to the timezone file of your choice in the /data/zoneinfo directory:
```
ln -s /data/zoneinfo/region/city /data/localtime
```
For example, to set the timezone to Asia/Kolkata:
```
ln -s /data/zoneinfo/Asia/Kolkata /data/localtime
```
Common timezone paths include:
- /data/zoneinfo/America/New_York
- /data/zoneinfo/Europe/London
- /data/zoneinfo/Asia/Tokyo
- /data/zoneinfo/Australia/Sydney
- /data/zoneinfo/UTC
Verify that the timezone is updated correctly:
```
ls -l /data/localtime
date
```
The symbolic link points to the new timezone file, and the date command displays the correct time for your timezone.
