+     * <pre>
+     * Scenario Outline: Time offset check for <LOCATION_NAME>
+     * Given my local country is <LOCATION_NAME>
+     * When I compare the time difference to GMT
+     * Then the time offset should be <OFFSET>
+     *  
+     * Examples: 
+     * | LOCATION_NAME | OFFSET |
+     * | London        | 1      |
+     * | San Fran      | 8      |
+     * </pre>
+     * 
+     * Will create a scenario named "Time offset check for London" for the first row in the 
+     * examples table.
