zoneinfo problem


I don't know if here is the right mail list.
I'm using stable/12. But there is a strangeness about zoneinfo files.

# ln -s /usr/share/zoneinfo/Etc/GMT+3 /etc/localtime
# date
Sat Dec 4 03:48:50 -03 2021

Above, I want to set the timezone to GMT+3 but date command shows as GMT-3

# rm /etc/localtime
# ln -s /usr/share/zoneinfo/Etc/GMT-3 /etc/localtime
# date
Sat Dec 4 09:49:07 +03 2021

When I set to GMT-3 then date command shows as GMT+3

I think there is a problem with zoneinfo files.

Best regards
