+
+clock_out is the function that gets called from customer.clock_out().
+It verifies that the customer is clocking out at the correct parkspot, and saves

+doesn't have to be calculated more than once.

+start and end are time points representing when someone clocks in and out. they're from the chrono

+save and update save and update info in the database.
+auto_increment pulls the highest id stored in the db, to be used in the constructor.
+
+start_to_int() is used to convert the start timepoint to an integer that can be saved in the
+database SQL datetime and chrono datetime don't seem the most compatible.
+
+We choose chrono because it's the recomended way from c++11 onwards, and is more typesafe and
+acurate https://stackoverflow.com/questions/36095323/what-is-the-difference-between-chrono-and-ctime
+but, it does not have parsing and formatting for human readable time.
+It will get that in c++20, but that's a little too late for us :(
