commit c6437ea3f9003a109d377d136901e2d5ef1cfc8a
Author: Chang chen <[email protected]>
AuthorDate: Tue Mar 31 10:01:00 2026 +0000

    Fix GlutenCastWithAnsiOnSuite failures #1-#3 for spark40/spark41
    
    - #1/#2 (TZ workaround): testGluten rewrite for "data type casting" and
      "cast string to timestamp" with withSQLConf to sync session timezone
    - #3: Add PRESERVE_CHAR_VARCHAR_TYPE_INFO=true in beforeAll
    - Exclude #4 (out-of-range to long) and #5 (Decimal to string) pending
      Velox C++ fixes
    
    Verified: spark41 95 passed/5 ignored, spark40 79 passed/5 ignored
