timezone issue

[mlcarson]

My server is in America/Los_Angeles timezone and is running the latest version of Debian stable. My nfcapd data files are getting the time/date correct. The nfsen-ng v0.3 is using UTC for the frontend graphs. It graphs the data in the correct spot but the current time is being taken from UTC so when I choose the 1 hour option, it'll show nothing because I'm 8 hrs in the future.

I've modified the /etc/php/8.2/apache2/php.ini file so that date.time is set to 'America/Los_Angeles' and restarted the apache2 server. I've also restarted the entire OS and no difference.

BTW, PHP 8.2 is the latest offered by Debian stable so I'm using that rather than 8.3 since 8.2 seemed to still be the minimum supported.

Well, I somehow "solved" this. The graphs are now just showing in UTC time (not exactly what I wanted) but the data is also mapped to UTC so when the last hour of data is shown it's now accurate. This might have been an issue with the /etc/php/8.2/cli/php.ini file. I modified that but hadn't restarted the cli.php daemon so maybe that was it...

So I guess the next question would be -- is there a way of displaying the graphs in the server's local timezone rather than UTC?

Can you try and set

nfsen-ng/backend/api/Api.php

Line 300 in dea3416

'tz_offset' => (new \DateTimeZone(date_default_timezone_get()))->getOffset(new \DateTime('now', new \DateTimeZone('UTC'))),

to 0 to see what happens in the frontend?

If I set it to zero, there's no difference. If I set it to -8 then the graph appears on local time since that's the offset from GMT.

@mlcarson can you try the latest master to see if it's better? We merged PR #105

Same issue, i was 2 hours in the past (for graphs, statistics…).

• AlmaLinux 9.4 ; Apache2 ; PHP 8.3

I solved this by modifying php.ini just as suggested by @mlcarson :

• Edit /etc/php.ini :

[Date]
; https://www.php.net/manual/en/timezones.php
date.timezone = Europe/Paris

• Restart php-fpm :

sudo systemctl restart php-fpm.service

• 👌
