I think it is time to improve Time Tracker database version tracking.
1) Database version is not stored anywhere. What we have in the footer is code version, which is usually different.
2) Database structure update process is currently awkward. It is prone to errors. People not doing the rights steps, or doing wrong steps.
It looks like we have to store DB structure version in the database itself and use it during updates - like to determine what the update should do.
