The Informix translator adjusts only time value according to server's timezone. Timestamp values are adjusted only if 'DatabaseTimeZone' property is set. Date values are not adjusted at all.
I am not sure what is Teiid's logic in this case. Is the difference between server's timezone and database's timezone taken into account? Or only the timezone of the database?
-------------------
Server's timezone - GMT+1
DatabaseTimeZone property - not overridden
Result:
| time | date | timestamp |
| 01:00:00 | 2000-01-01 | 2000-01-01 00:00:00.0 |
Server's timezone - GMT+5
DatabaseTimeZone property - not overridden
Result:
| time | date | timestamp |
| 05:00:00 | 2000-01-01 | 2000-01-01 00:00:00.0 |
Server's timezone - GMT+5
DatabaseTimeZone property - GMT+1
Result:
| time | date | timestamp |
| 01:00:00 | 2000-01-01 | 2000-01-01 04:00:00.0 |
Server's timezone - GMT+5
DatabaseTimeZone property - GMT-1
Result (int this case
| time | date | timestamp |
| 23:00:00 | 2000-01-01 | 2000-01-01 06:00:00.0 |
