When iterating journal entries with --until (forward scan) or --since (reverse scan), the code used continue instead of break after crossing the time boundary. Since sd_journal_seek_realtime_usec() is called before the loop to position at the start of the range, sd_journal_next()/previous() returns entries in monotonically increasing/decreasing time order. Once an entry's timestamp exceeds arg_until (or falls below arg_since in reverse), all subsequent entries will also be out of range. Using continue caused the entire remaining journal to be scanned unnecessarily. journalctl uses break for the identical pattern in src/journal/journalctl-show.c.
