DB2Platform defines the query:

SELECT CURRENT TIMESTAMP FROM SYSIBM.SYSDUMMY1

to obtain the database timestamp. However, depending on the DB2 z/OS configuration and JDK, this may not be supported.

Issue 1779: Add DB2zOS support for UNICODE Timestamps (#1783)
dabf4d0 
for #1779

For non-IBM JDKs, against DB2 zOS, the existing test `org.eclipse.persistence.jpa.test.version.TestVersioning.testTemporalVersionField1()` fails:
```sql
