To get timezones to work, there are several things needed.

1) strftime.c, asctime,c, localtime.c need to be changed.
   See the ones in uClinux/uC-src/real/date.

2) /etc/localtime needs to point to the zoneinfo file.
   cd uClinux/romdisk
   "become root"
   mkdir etc
   cd etc
   ln -s /var/zoneinfo/CST6CDT localtime

3) Create the zoneinfo files.  In the uClinux/romdisk/etc directory, copy
   in ../root/etc/rc, or if it already exists, add in the following before
   the "date" command is executed.
   
   echo "create zoneinfo files"
   mkdir /var/zoneinfo
   cd /etc/datfiles
   /bin/zic -y /etc/datfiles/yearistypecopy.sh -d /var/zoneinfo -L /dev/null northamerica

4) Copy in the datfile directory from this directory.  In uClinux/romdisk/etc
   directory:
   
   cp -r uClinux/uC-src/real/zoneinfo/datfiles uClinux/romdisk/etc/
