The following list was kindly given to the PTB by the Deutsches Hydrographisches Institut, Hamburg. The information agrees, except for the year 1945, with that found in Grimm, Hoffmann, Ebertin, Puettjer, "Die Geographischen Positionen Europas", Ebertin-Verlag, Freiburg 1994 (GHEP). GHEP states for all years the issues of the Reichsgesetzblatt or the pertinent session of the allied control council which allows to check the validity of the dates given below. Therefore information from GHEP has been used for the tables shown below. According to GHEP, rules in the three western zones differed from those in Berlin and the Sowjet zone (see section (c) below).
