An administrator can change the following location settings in Administration > Site administration > Location > Location settings.
Time zone settings
The time zone is used to help convert the raw timestamps in the database to human readable dates and times, for the user who is requesting the page.
Default time zone
Use this to set the default time zone for your site. This should be the time zone that most users use, or if that is difficult, where you When available, choose the Area/Location that is proper for you rather than use the UTC settings. These names are standardized by the IANA.
Note: As of Moodle 2.9, the older setting and button to allow you to update time zone codes from Moodle.org has been replaced with standard PHP date and time code. If your PHP version is over 6 months old, time zone data should be updated using the PECL timezonedb package.
If a particular time zone is forced, users will see the name of the time zone on their edit profile page and will be not be able to change it. If you wish to allow individual users to choose their own time zone, leave this at the default "Users can choose their own time zone."
Select the country to appear by default on a new user account page form.
Enter a default city for new user profiles. This may be left blank.
IP address lookup
GeoLite2 City MaxMind DB
Location of GeoIP City binary data file. This is a non-invasive way to determine geographical and other information about Internet visitors in real-time. This file is not part of Moodle distribution and must be obtained separately from MaxMind.
There is a GeoIPLite version for free at http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz. Extract the GeoLiteCity.dat file and upload it to /moodledata/geoip/GeoLiteCity.dat.
Since Moodle 3.2 looking up IPv6 addresses using the GeoLite2 database from Maxmind is supported (more info here). This replaces the existing GeoLite legacy database used in previous versions and the new GeoIP2 database will need to be installed to use this functionality. This GeoLite2 database can be downloaded from http://geolite.maxmind.com/download/geoip/database/GeoLite2-City.mmdb.gz
You can check to see if the GeoIP data file is available to Moodle by going to: Administration > Site administration > Location > Location settings, under IP Address Lookup.
Google Maps API V3 key
After updating the information in this section, IPs that are displayed as a link, such as in reports, when clicked will open new window with a Google Map indicating the location of the IP, if found and if not a private address.
All country codes
This is the list of countries that may be selected in various places, for example in a user's profile. If blank (the default) the list in countries.php in the standard English language pack is used. Otherwise, you can specify a comma-separated list of codes, for example 'GB,FR,ES' in ISO-3166-1 format.
The list of countries is based on the ISO 3166 list of official country short names, but is not exactly the same. See the comment in MDL-56181 for more details.
