You can restore transactions from a transaction log up to and including a point in time in the transaction log. After the point in time is reached, recovery from the transaction log is stopped. To find dates and times of transactions, check your client application event log.
If the specified point in time is later than the time contained in the most recent transaction log being restored, then the restore operation succeeds, but a warning is generated and the database remains in an intermediate state. If the specified point in time is before the time contained in the transaction log or logs being restored, no transactions are restored.
