    import com.sleepycat.db.*;

    public void set_tx_timestamp(java.util.Date timestamp)
    	throws DbException;

# Description

Recover to the time specified by timestamp rather than to the most current possible date. Note that only the seconds (not the milliseconds) of the timestamp are used

Once a database environment has been upgraded to a new version of Berkeley DB involving a log format change (see Upgrading Berkeley DB installations, it is no longer possible to recover to a specific time before that upgrade.

The DbEnv.set_tx_timestamp interface may only be used to configure Berkeley DB before the DbEnv.open interface is called.

The DbEnv.set_tx_timestamp method throws an exception that encapsulates a non-zero error value on failure.

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  It is not possible to recover to the specified time using the log files currently present in the environment.
