FAQ concerning the Time Zone Database update

Q: What should I do when my time zone shift from the UTC has changed?

A: Please update the time zone database for the third party components, used by UTM5 for receiving or displaying the time and date information.

 

Q: Which third party components are used by UTM5 for receiving the time and date information?

A: UTM5 Core, UTM5 RADIUS, UTM5 Send CDR and UTM5 URFA Client use the system time zone database for that purposes.

 

Q: Which third party components are used by UTM5 for displaying the time and date information?

A: Administrator's, Dealer's and Cashier's interfaces use the JRE time zone database for displaying the time and date information. The web interface uses the system time zone database for displaying the time and date information (the time zone is set in the PHP configuration file in that case).

 

Q: What should I do after updating the time zone database?

A: Make sure that the time and date are displayed correctly and make sure that the accounting periods have the correct end time and date. If the end time and date is incorrect, set it manually.

 

Q: What should I do when the time and date in the administrator's interface is incorrect?

A: Check, the time zone in the administrator's interface settings. If the time zone is set to "Server Time Zone", select the correct time zone manually.

 

Q: How do I update the time zone database for the recommended operation systems?

A: In CentOS 5 and CentOS 6 use the following command:

	yum install tzdata


In Linux Debian Wheezy use the following command:

	apt-get update
apt-get install tzdata


Make sure that the installed version of the tzdata package contains an up-to-date information about the time zone used on your server.

 

Q: How do I update the time zone database for the JRE?

A: Use the Java Time Zone Updater Tool. You can find and download it on the following page: http://www.oracle.com/technetwork/java/javase/downloads/index.html

 

Make sure that the installed version of the time zone database contains an up-to-date information about the time zone used by the Administrator's, Dealer's and Cashier's interface.

 

Q: How do I make sure, that the installed version of the time zone database contains an up-to-date information about the time zone used by my server?

A: The time zone database used by the recommended operation systems and JRE is based on the Time Zone Database data. Download the latest version of the Time Zone Database from the official site http://www.iana.org/time-zones and see the change log in the NEWS file to check if the version is up-to-date. E.g. the changes to Russian time zones that took effect on the 26th of October 2014, appeared in the Time Zone Database version 2014f and are present in later versions.

 

Q: What should I do if the time and date in the user's web interface is incorrect?

A: Set the correct time zone in the date.timezone parameter in the PHP configuration file.

 

Q: What should I do if the operation system or the JRE, I'm using, are not from the recommended list?

A: Please contact your system administrator or the operation system or the JRE technical support. These operation systems or JREs may use some different ways to maintain their time zone database. E.g. to update the Windows OS time zone database for the changes to Russian time zones that took effect on the 26th of October 2014, one has to install the KB2998527 update package, available at http://support.microsoft.com/kb/2998527/en-US
