You also need to be aware of different systems and how they work with time references,.

So it is important to know what function is calculating time from this reference and its why a data should be stored as a datetime stamp in SQL format so that the database will at least have stored the correct time reference so that when an update or changes alter the time functions, the results will be the same and not altering the time reference.
