 DESCRIPTION: Time Zone Definition Block
 DSECT      : TZDBK
 FUNCTION   : This DSECT maps the definitions of local time
              zones based on each zone's deviation from the
              standard time at longitude 0.  This standard
              time is known as Universal Coordinated Time,
              abbreviation UTC.  This standard was formerly
              known as Greenwich Mean Time, abbreviation GMT.
 LOCATED BY : PFXSYS -> SYSCM
              SYSZANCR -> TZABK  (Time Zone Anchor Block)
              TZATZD -> TZDBK
              <TZDFWD -> TZDBK, until TZDFWD = 0>
