Issue related to web log time and date

[noc2]

Recently I have upgrade firmware version 5 patch 4 from version 4 MR3 patch 7 in fortianalyer 1000C. I am getting garbage value in place of date and time in my store device, not in Analyzer. This issue after a upgrade.

there was no garbage value in version 4 MR3 patch 7 in my storage device.

One thing I notice that I use CSV log format in version 4. but when I enter command for CSV log format in version 5 then my log uploading will stop in my storage device

I attach log print screen of version 4 and version 5

Hi Noc.

Welcome to the forums.

Patch notes for 5.0.4 outlines the recommended steps to follow when performing an upgrade, specifically it recommends upgrading to 5.0.1 first before jumping to 5.0.4.  Attached is an edit pic showing what I think may be related to your issue.

Thank you for support

But this command is not useful for me. I try but I doesn't get output.

Is there any suggestion ?
