to emulate this in DB2.

> Key: OAK-3645
> URL: https://issues.apache.org/jira/browse/OAK-3645
> Project: Jackrabbit Oak
> Issue Type: Technical task
> Components: rdbmk
> Affects Versions: 1.3.10, 1.2.8, 1.0.24
> Reporter: Julian Reschke
> Assignee: Julian Reschke
>
> We use {{CURRENT_TIMESTAMP(4)}} to ask the DB for it's system time.
> Apparently, at least with DB2, this might return a value that is off by a
> multiple of one hour (3600 * 1000ms) depending on whether the OAK instance
> and the DB run in different timezones.
> Known to work: both on the same machine.
> Known to fail: OAK in CET, DB2 in UTC, in which case we're getting a
> timestamp one hour in the past.
> At this time it's not clear whether the same problem occurs for other
> databases.
