The length of time Replication Option waits between the time of
    the last failed attempt and the time of the next retry attempt.
    The RETRY EVERY delta-time clause is optional and can only be
    specified if the RETRY count TIMES clause is included.

    If you specify RETRY count TIMES in the schedule definition,
    but do not specify RETRY EVERY delta-time, Replication Option
    attempts the retry immediately. See the description of the start-
    date-time parameter earlier in this section for valid delta-time
    values.
