+# Anuario del Observatorio Astronómico de Madrid (2013, in Spanish).
+# http://astronomia.ign.es/rknowsys-theme/images/webAstro/paginas/documentos/Anuario/lahoraoficialenespana.pdf
+# As this source says that historical time in the Canaries is obscure,

+#
+# In the 1918 and 1919 fallback transitions in Spain, the clock for
