Which argues for including the local time when the event will take place. If
you want to mandate that the time also appear in UTC, great, but it's quite
important that the local time also be there.
And local time should be normative to deal with such unforeseen
circumstances as a papal visit. From the southamerica file in the TZ
database:
# From Daniel C. Sobral (1998-02-12):
# In 1997, the DS began on October 6. The stated reason was that
# because international television networks ignored Brazil's policy on DS,
# they bought the wrong times on satellite for coverage of Pope's visit.
# This year, the ending date of DS was postponed to March 1
# to help dealing with the shortages of electric power.

Good point. I agree.
