Fix for this problem.
Proposed patch. This reflects my understanding of current situation:
+ No DST is introduced
+ The timezone will change from -4:00 to -4:30. At 24:00 of 23 Sep, the
clocks will move back to 23:30 of 23 Sep
+ New timezone should be called Hora Legal de Venezuela, and the time zone
abbreviation is accordingly HLV. This is best effort guess, not an official
resolution (as of yet).
