 I'm unable to understand why my timezone is different on both FMG and Fotigate.

 

I've checked all ADOMs and it is showing same timezone: IST under each ADOM  despite timezone correctly mentioned in each fortigate firewall. I wonder it mean something else when used in FMG? or still it stands as Indian standard time? why its not showing BST? I've checked FMG system time and zone under settings and its correct so not sure what is the issue? Please can someone shed some light on this? 

Under FortiManager -> Device Manager -> Manage device and under System information: 

FMG timezone for the same Fortigate

System time showing e.g Fri Jul 18 12:58:50 2025 IST

 

were on the same firewall when I am checking timezone its showing

Probably I'm not a proper person to comment on this since I don't reside either UK or Ireland. So you might want to ignore.
But I think it's more political than a technical issue. While both countries share the same time zone, they have different way to call summer time, British Summer Time (BST) and Irish Standard Time (IST). I'm guessing the FMG shows "GMT" for "set timezone 25" when the summer time ends.
