Steps to reproduce:

1. Run Zabbix agent 2
2. Run zabbix_get with any Oracle key, e.g.:

zabbix_get -s localhost -p 10050 -k oracle.ping[localhost:1521,ZABBIX_MON,zabbix,xe] 

Result:
In the agent's console the warning appears:

godror WARNING: discrepancy between SESSIONTIMEZONE ("+03:00"=300) and SYSTIMESTAMP ("+00:00"=0) - set connection timezone, see https://github.com/godror/godror/blob/master/doc/timezone.md

Expected:

No warning is expected to appear.

Note:

1. The same appears if run the agent with Oracle test key:

{zabbix_agent2 -c /home/leo/zbx/testconf/zabbix_agent2.conf -t oracle.ping[localhost,ZABBIX_MON,zabbix,xe]}

In this case (bacause of the warning) result is not JSON anymore, e,g, <agent with testkey oracle.tes.stats>| jq returns:

jq: parse error: Invalid numeric literal at line 1, column 16

 2. The issue was introduced with the ticket ZBX-22374 where Oracle plugin's library github.com/godror/godror was upgraded to v0.48.0.
