Don't use 'zic' - precompiled time-zone-info files already exist.  They
are in /usr/lib/zoneinfo.  Several timezones have multiple names.  To see
them, do the following:

	cd /usr/lib/zoneinfo
	find . -links +1 -ls | sort | more

There is no need to do anything manually if you make
/usr/lib/zoneinfo/localtime be a hard link to
/usr/lib/zoneinfo/US/Eastern.
