- Based on this suggestion The Real Time Alliance Statistics screen has been renamed to Detailed Alliance Statistics. The detailed alliance statistics screen now includes additional information such as alliance wide purchases of land, infrastructure, technology, nukes, soldiers, tanks, cruise missiles, the number of nations both in war mode and in peace mode, the number of nations in anarchy, and the count of alliance wide improvements and wonders. After much consideration on whether to provide such detailed alliance stats I decided that all of the information provided in this update is already visible in the game so it just makes sense to make the information a little easier to access. The results of alliance queries are now stored in the game database for fast retrieval after the initial query is run and to allow all alliances with 20 or more members, not just the top 12 sanctioned alliances, to be displayed in the updated All Alliances Display screen. Detailed Alliance Stats will remain static in the database for 12 hours. Once 12 hours has passed since the last query was run for an alliance the records will be updated and a new 12 hours will start. It will take a little time for all the active alliances in the game to be populated into the database. If a query is not run on an alliance for 7 days it will be automatically pruned from the database.
This should explain why the time changes... Unless someone pulls up your alliance 12hrs and 1min after the last time it was updated, then the time will gradually blow out longer and longer than 12hrs.
