The time field in the Systems file has an optional "retry" subfield.

	daytime[;retry][/grade]

Retry specifies the number of mintes before retrying a failed attempt.
According to the SunOS 4.1 (which uses HDB) documentation:

	In the absence of the ;retry entry, an exponential backoff algorithm
	is used (starting with a default wait time that grows larger as the
	number of failed attempts increases).  The initial retry time is 5
	minutes, and the maximum retry time is 23 hours.  If ;time is
	specified, that will always be the retry time.  Otherwise, the backoff
	algorithm is used.

Read the documentation and find out.  You can specify a maximum grade of
file to send, what UUCP protocol to use, etc.
