# 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.

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.
