DB_ENV->set_tx_timestamp |
#include <db.h>int DB_ENV->set_tx_timestamp(DB_ENV *dbenv, time_t *timestamp);
int DB_ENV->get_tx_timestamp(DB_ENV *dbenv, time_t *timestampp);
Recover to the time specified by timestamp rather than to the most current possible date.
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 database environment.
The DB_ENV->set_tx_timestamp method may not be called after the DB_ENV->open method is called.
The DB_ENV->set_tx_timestamp method returns a non-zero error value on failure and 0 on success.
The timestamp parameter should be the number of seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time; that is, the Epoch.
The DB_ENV->set_tx_timestamp method may fail and return one of the following non-zero errors:
The DB_ENV->get_tx_timestamp method returns the recovery timestamp.
The DB_ENV->get_tx_timestamp method may be called at any time during the life of the application.
The DB_ENV->get_tx_timestamp method returns a non-zero error value on failure and 0 on success.
