graphs displaying wrong date/time

[jpreed00]

The system clock is correct. Yet zabbix is displaying data on the graphs from about 7 hours in the future. If it truly was how my servers were going to be operating 7 hours in the future, that would be awesome. However, I fear the date is simply being improperly displayed.

Any ideas about what would cause this and how I might go about fixing it?

Thanks!

A few things... What is the hardware clock set to on your server (local or UTC), then what is the timezone for your server? Also what is the timezone in your php.ini file.

It is important that your local timezone be set correctly and display the time correctly on the commandline, and that the php.ini file match. Php however does not adjust the time as it uses it from the system clock.

Lastly what is the time and timezone on the client you are using to view the graphs?

Zabbix Host:

linux-epfq:~ # hwclock --show
Sun Jan 23 15:19:55 2011 -0.285126 seconds
linux-epfq:~ # date
Mon Jan 24 15:20:16 EST 2011
linux-epfq:~ # date -u
Mon Jan 24 20:20:28 UTC 2011


The client is also set correctly.

PHP time zone was set for Europe/Riga. There are, apparently, several php.ini files floating around the Zabbix appliance. I had already changed one of them--but it was the wrong one. That fixed one of the issues. The time is now displaying correctly.

Now the graphs are displaying 1 full day ahead. See attached screenshot.

Edit: Just saw that the date is showing one full day ahead of the hwclock. Missed that before. Any idea why that might be?

Alrighty, got it figured out now.

There was some tutorial on the net that had you resetting the system clock from the hardware clock using:

hwclock --systohc

That command actually copies the system time to the hardware clock. (As the name implies...)

The actual command you want once setting the hardware clock and timezone correctly is:

hwclock --hctosys

For those looking how to set the proper time for their Zabbix installation, these are the steps you have to follow:

1. Set your php.ini (for the zabbix appliance, the path is /etc/php5/apache2/php.ini)
Find the line: date.timezone = <some timezone> and change it appropriately.

2. Change the system timezone.
Follow this tutorial: http://www.wikihow.com/Change-the-Timezone-in-Linux

3. If necessary, update the hardware clock, then reflect the changes back to the system clock.
hwclock --set --date="MM/DD/YYYY HH:MM" --localtime
hwclock --hctosys

Thank you. You reply gave me pointers where to look.
What solved my timezone problem with Version 3.2 was setting php_value date.timezone America/Toronto in /etc/apache2/conf-available/zabbix.conf file

For v3.2 also please make sure that /etc/apace2/conf-enabled/zabbix.conf file should be amended as well.

In <IfModule mod_php5.c> block, find entry php_value date.timezone Europe/Riga and change it according to your Timezone.

In <IfModule mod_php7.c> block, find entry php_value date.timezone Europe/Riga and change it according to your Timezone.

for version 5.0 change in

# grep timezone /etc/php-fpm.d/zabbix.conf
php_value[date.timezone] = Europe/Riga

I've had the same problem...
