DB_ENV->set_tx_timestamp(DB_ENV *dbenv, time_t *timestamp);
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; that is, 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 DB_ENV->set_tx_timestamp method configures operations performed using the specified
DB_ENV handle, not all operations performed on the underlying
The DB_ENV->set_tx_timestamp interface may not be called after the DB_ENV->open
interface is called.
The DB_ENV->set_tx_timestamp method returns a non-zero error value on failure and 0 on success.
The DB_ENV->set_tx_timestamp method may fail and return a non-zero error for the following conditions:
- 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.
The DB_ENV->set_tx_timestamp method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB_ENV->set_tx_timestamp method may fail and
in which case all subsequent Berkeley DB calls will fail in the same way.
