DbEnv::set_tx_timestamp

#include <db_cxx.h> int DbEnv::set_tx_timestamp(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 method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 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.
