Incorrect Server Time on the "Time Conditions" Page

As this took a while to discover, I figured I would document this for anyone else with this issue, and for my own future reference.


  1. system time was correct and in the correct time zone.
  2. Using the “speaking clock” feature (*60 on this system), the time was correct.
  3. The “Server Time” displayed on the “Time Conditions” page was incorrect and off by exactly 2 hours.

Since the time was exactly 2 hours off it is clearly a time zone issue, however the issue has nothing to do with Asterisk. PHP has a separate time zone setting in “/etc/php.ini”.

Edit the php.ini file and modify the “date.timezone” parameter to match the system time zone as found in “/usr/share/zoneinfo/”


$ grep timezone /etc/php.ini
date.timezone = America/Chicago

If you are having any other time zone related issues, here are the standard settings for most Linux operating systems: (Examples all use US Central time zone)

  1. Create a symlink from the time zone file to “/etc/localtime”. you may need to delete the file if it already exists.

       $ ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime
  2. Add a time zone environment variable.

  $ echo "export TZ=America/Chicago" >> /etc/profile
  1. On some Red Hat and similar systems, the time zone is also stored in “/etc/sysconfig/clock”. Edit this file and set the correct time zone.
  $ cat /etc/sysconfig/clock

Note that a reboot is required to completely enable the changes made to system time zone settings.

Works great!

On Debian systems you may need to run

diff -s /etc/localtime /usr/share/zoneinfo/cat /etc/timezone

to check the current time zone, eg:

diff -s /etc/localtime /usr/share/zoneinfo/cat /etc/timezone

Files /etc/localtime and /usr/share/zoneinfo/Australia/Brisbane are identical
