This sets time zone for the java process. For postgres, it is already set in the config file /opt/yugabyte/software/active/pgsql/conf/postgresql.conf as
timezone = 'UTC'. Verified it by
```
[root@ip-10-9-89-26 bin]# ./psql -U postgres -d yugaware -h localhost
psql (14.17)
Type "help" for help.
yugaware=# show timezone;
