    int
    DBENV->set_tx_timestamp(DB_ENV *dbenv, time_t *timestamp);

# Description

Recover to the time specified by timestamp rather than to the most current possible date. The timestamp argument should be the number of seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time, i.e., the Epoch.

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 function returns a non-zero error value on failure and 0 on success.

# 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.
