The procedure for updating the timezone database on the ST5xxx NAS is as follows.

1. Download the current timezone database files from ftp://elsie.nci.nih.gov/pub/. The desired file will have a name of the form tcdataYYYYn.tar.gz, for example; tzdata2007c.tar.gz
2. Use gunzip and tar to extract the database files.
   The extracted files reference various continents and regions as shown below. There are currently eleven regions.
   • africa
   • antarctica
   • asia
   • australasia
   • etcetera
   • europe
   • northamerica
   • pacificnew
   • solar87
   • southamerica
3. If a user wishes to update to the latest timezone rules, they will need to copy the group desired into the /cvol/nf1/tz or /cvol/nf2/tz directory depending on the value in /cvol/defstart. This will truncate the filenames to 8 characters and the area names will appear as foillows:
   
   africa, antarcti, asia, australa, etcetera, europe, northame, pacificn, solar87, southame
   
   After the area, i.e. northame, has been copied into the destination directory, the user must run:
   
   > zic /cvol/nf2/tz/northame (for North America)
   
   to extract the specific timezones from the continent.
   
   Rebooting is not required.
