   Perhaps the instant of the switch to time zone
   time for Europe/Madrid could also be corrected.

   The Royal Decree of 1900-06-26 quoted by Planesas, online at
   says in its article 5 (my translation):
       These dispositions will enter into force beginning with the
       instant at which, according to the time indicated in article 1,
       the 1st day of January of 1901 will begin.
   The time in article 1 is GMT = WET. Thus:

     - Zone   Europe/Madrid   -0:14:44  -  LMT  1901 Jan  1  0:00s
     + Zone   Europe/Madrid   -0:14:44  -  LMT  1900 Dec 31 23:45:16
