ID:          issue-6013
ISSUE:       6013
TITLE:       Date-time parsing is very weak
DESCRIPTION:
  Parser changed after following fixes:
    - CORE-6427 - Whitespace as date separator causes conversion error.
    - CORE-6429 - Timezone offset in timestamp/time literal and CAST should follow SQL standard syntax only.
  See: https://github.com/FirebirdSQL/firebird/commit/ff37d445ce844f991242b1e2c1f96b80a5d1636d
  Adjusted expected stdout/stderr after discuss with Adriano.
JIRA:        CORE-5750
FBTEST:      bugs.core_5750
