On Unix/Linux, it litterally would be as simple as editing the source
zonetab for the US, setting an ending date for the the current rule,
starting a new rule with the new dates. Then performing a ZIC command to
compile the rule file into a binary and ship the binary around as a file.
Someone familiar with the
file format could probably do it in 30 minutes or less.
