   Many thanks for the careful work!

   I have checked the references you gave and offer the following comments:

   • source 
     documents only the step back on 1949-10-02 from 03 hours to 02 
hours, but
     the start of summer time in 1949 is not documented in the sources 
you quote.

   • Also, the step back on 1942-11-02 is not documented in the sources.

   • sources 
     seem to be inconsistent: both mention two different date for the 
switch back
     in autumn (1981-09-26 and 1981-09-27 resp 1983-09-24 and 1983-09-25); I
     could make sense of different dates for the steps forward (from 24 
h to 01 h)
     but not for the steps back.

   • source 
     gives the steps for 1981, and should therefore placed later in the 
zic source.
     Do you have a source for the steps in 1980?

   I do not read Hungarian, so I easily may have overlooked something in 
   sources. Thanks again for the extensive work!
