Feel free to forward this to tz. I don't need to see any responses
(I'll see them in the tz archives eventually anyway).
This is all that tzdata has on Peru, unless it's been updated since
the last time I looked. (I can't recheck it from home, because
elsie.nci.nih.gov has not accepted FTP connections from shell.vex.net
for several months.)

Now, it's bizarre enough to see an equatorial country falling victim
to DST in the first place, but these things happen -- but the dates
shown from 1987 to 1994 make this case even weirder.
However, here is evidence that the above is not the whole story.

When we were in Peru in 1985-1986, they apparently switched over
sometime between December 29 and January 3 while we were on the Amazon.

I have already contacted Evelyn by email and she has confirmed that
the years she mentions were the correct ones. So the obvious guess
is that the same January 1 - April 1 pattern occurred in 1986, and
perhaps in some other years around then.
