Extract the package contents using the program 7-Zip (freely available from http://www.7-zip.org).
Find the file for your location in the extracted directory in
usr/share/zoneinfo/
, e.g.usr/share/zoneinfo/Africa/Casablanca
for Morocco.
On Linux
Update your system time zone information with these commands:
sudo apt-get update
sudo apt-get install tzdata
Find the file for your location in the system directory
/usr/share/zoneinfo/
, e.g./usr/share/zoneinfo/Africa/Casablanca
for Morocco.

On a device, you can verify the transfer and activation of the new time zone information files:
In the Local Terminal, enter
grep 'timezone_config' /var/log/messages
On IGEL Linux version 10.x, use: journalctl | grep 'timezone_config'
The output should look like the following:
Feb 27 11:28:13 (none) timezone_config: loading /wfs/zoneinfo/Casablanca to /usr/share/zoneinfo/Africa/Casablanca
Feb 27 11:28:13 (none) timezone_config: loading /wfs/zoneinfo/Casablanca to /usr/share/zoneinfo/posix/Africa/Casablanca
Feb 27 11:28:13 (none) timezone_config: configure timezone Africa/Casablanca
