I reply myself on this point. I have understood that the zones
definitions are taken from here:

ftp://elsie.nci.nih.gov/pub/

Thus, this bug can not be noticed by any Unix-based operating system
that has not made some additional control of these definitions, as also
it happened to OpenBSD.

It is strange to me that taking these definitions from the same source,
in Etch/Lenny the change would take place before Sid.

I believe that until the mantainers of the zones definitios file of the
elsie FTP are not informed into this inconsistency ---a change of
timezone that never was official by the Argentine state and it was
applied by error to these definitions--- we will have to be cautious so
that after to have corrected the problem in our Unix-based operating
systems there are no other updates that can undo them.

Thanks for the patch, Marga :-)

Regards,
Daniel
