ISSUE:       6480
TITLE:       RDB$TIME_ZONE_UTIL package has wrong privilege for PUBLIC
DESCRIPTION:
  Thanks Adriano for suggestion about this test implementation.
  We create non-privileged user ('tmp$c6236') and do connect of him
  with trying to use package function rdb$time_zone_util.database_version().
  It must pass without any errors (result of call no matter).

  Confirmed exception on 4.0.0.1714: no permission for EXECUTE access to PACKAGE RDB$TIME_ZONE_UTIL
  Checked on 4.0.0.1740 SS: 1.400s - works fine.
  ::: NB :::
  Command 'SHOW GRANTS' does not display privileges on system objects thus we do not use it here.
