How to solve time synchronization problem on Vicidial

---

When timezone is set differently in Server, Vicidial database, and in PHP you will receive the following error.

There is a time synchronization problem with your system, please tell your system administrator

To resolve this you need to set the same timezone for the Server, Vicidial database, and in PHP.

To check Server timezone.

timedatectl

Output:

vicibox9:~ # timedatectl
      Local time: Tue 2021-06-08 14:02:11 UTC
  Universal time: Tue 2021-06-08 14:02:11 UTC
        RTC time: Tue 2021-06-08 14:02:11
       Time zone: UTC (UTC, +0000)

And also check in /etc/php7/apache2/php.ini.

Output:

vicibox9:~ # cat /etc/php7/apache2/php.ini | grep timezone
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone =
vicibox9:~ #

Note: For the above timezone make changes if needed and make sure both are in the same timezone!!

If the issue persists after the above changes are made, use the following command check and compare the timezone values in the Server, PHP, and Vicidial database.

echo "SELECT server_ip, UNIX_TIMESTAMP(last_update),UNIX_TIMESTAMP(db_time) from server_updater" | mysql -uroot asterisk && php -r "date_default_timezone_set('America/New_York'); echo 'php time: '.date('U');" && echo ""

Output:

vicibox9:~ # echo "SELECT server_ip, UNIX_TIMESTAMP(last_update),UNIX_TIMESTAMP(db_time) from server_updater" | mysql -uroot asterisk && php -r "date_default_timezone_set('America/New_York'); echo 'php time: '.date('U');" && echo ""
server_ip       UNIX_TIMESTAMP(last_update)     UNIX_TIMESTAMP(db_time)
193.29.57.151   1623161611      1623161611
php time: 1623161612

To resolve this issue run the following script.

/usr/share/astguiclient/AST_update.pl

Output:

vicibox9:~ # /usr/share/astguiclient/AST_update.pl
SHOW CHANNELS format: 1
LOOKING FOR Zap/DAHDI clients assigned to this server:
LOOKING FOR IAX2 clients assigned to this server:
LOOKING FOR SIP clients assigned to this server:

Zap Clients:  |
IAX2 Clients: |
SIP Clients:  |gs102|gs102@gs102|
pattern match timed-out at /usr/share/astguiclient/AST_update.pl line 470

Note: In the above output we can see the error pattern match timed-out at /usr/share/astguiclient/AST_update.pl line 470,

• This error occurs due to the Asterisk server response doesn’t match the regex pattern.

To resolve this issue open the following files and find the line $t->waitfor('/[0123]\n$/');

• /usr/share/astguiclient/AST_update.pl
• /usr/share/astguiclient/AST_update.pl
• /usr/share/astguiclient/AST_update.pl

And replace it with,

$t->waitfor('/[0123456789]\n$/');

or

$t-waitfor('/Asterisk Call Manager.+\n$/');

After the changes are made re-run the script /usr/share/astguiclient/AST_update.pl

And confirm the changes by running the following command.

echo "SELECT server_ip, UNIX_TIMESTAMP(last_update),UNIX_TIMESTAMP(db_time) from server_updater" | mysql -uroot asterisk && php -r "date_default_timezone_set('America/New_York'); echo 'php time: '.date('U');" && echo ""

Output:

vicibox9:~ # echo "SELECT server_ip, UNIX_TIMESTAMP(last_update),UNIX_TIMESTAMP(db_time) from server_updater" | mysql -uroot asterisk && php -r "date_default_timezone_set('America/New_York'); echo 'php time: '.date('U');" && echo ""
