<h1>Description</h1>
<p>Recover to the time specified by <b>timestamp</b> rather than to the most
current possible date.
Note that only the seconds (not the milliseconds) of the <b>timestamp</b>
are used
<p>Once a database environment has been upgraded to a new version of Berkeley DB
involving a log format change (see <a href="../ref/upgrade/process.html">Upgrading Berkeley DB installations</a>), it is no longer possible to recover
to a specific time before that upgrade.
<p>The DbEnv.set_tx_timestamp method configures operations performed using the specified
<a href="../api_java/env_class.html">DbEnv</a> handle, not all operations performed on the underlying
database environment.
<p>The DbEnv.set_tx_timestamp interface may not be called after the <a href="../api_java/env_open.html">DbEnv.open</a>
interface is called.
<p>The DbEnv.set_tx_timestamp method throws an exception that encapsulates a non-zero error value on
failure.
<h1>Errors</h1>
<p>The DbEnv.set_tx_timestamp method may fail and throw an exception encapsulating a non-zero error for the following conditions:
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
<p>It is not possible to recover to the specified time using the log files
currently present in the environment.
</dl>
<p>The DbEnv.set_tx_timestamp method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the DbEnv.set_tx_timestamp method may fail and
throw a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>,
in which case all subsequent Berkeley DB calls will fail in the same way.
