Copying old logs with server_time = CURRENT_DATE() means we can try Piwik in a "production" like environment. Running the script to copy the last week of data, into today, will effectively generate an unusual load on Piwik.
This script will allow to quickly generate huge piwik logs from a starting database (even with old data).
Script only used by developers
(In ) Fixes #2626
I'm hoping to extend it later to generate this huge load over multiple days, as well as generating over a given number of websites.
