Is that the timezone you want or did you just copy it from that guide? My CentOS system shows Kolkata under Asia, not Africa. PHP has it under Asia as well.

i just copied (lol), but I inset a comment (:wink: on this line under the /etc/php/8.0/apache2/php.ini

Try “grep -r Africa /usr/share/zoneinfo/” and identify a city which is in the
correct timezone for your location, and use that name instead of
“Africa/Kolkata”.

You can only select from cities in the list - you can’t just put in the city
you are in or nearest to, and hope that the system knows where that is :slight_smile:

root@root:/home/secops# more /etc/php/8.0/apache2/php.ini
[PHP]

date.timezone = America/Manaus
cgi.fix_pathinfo=0

; PHP attempts to find and load this configuration from a number of locations.
