Unless your data represents something abstract, there is no reason it should not have an associated time-space tag attached to it. Doing so will ultimately make it easier to run deep associative analytics on your data (e.g. How many small businesses close to Wall Street were impacted by the 2008 crash?). Now that I think about it even abstract notions are associated to physical entities which probably means they should be tagged in time and space.
I repeat there is no reason it should not have an associated time-space tag attached to your database records.
