     It is the task of the tz database to represent the
     civil time used at a location as faithfully as possible.
     Documents issued under the current administration at
     that location must be considered for that task,
     regardless of the legality of that administration.

     This abstract position may be difficult to take,
     especially if you are personally involved. But it is
     absolutely necessary in order to reliably provide
     the desired service, for instance to the cell phone
     users living in Simferopol.
