dbscan(A)
Error using dbscan
Expected X to be one of these types:

single, double, logical

Instead its type was duration.

As with your earlier question, convert your durations to numeric values using minutes. You can later convert it back to durations also using minutes.
A = duration('00:01:01')
A = duration
00:01:01
B = minutes(A)
B = 1.0167
C = minutes(B)
C = duration
1.0167 min
C.Format = 'hh:mm:ss'
C = duration
00:01:01

datenum is not recommended. To represents points in time, use datetime arrays. To represent elapsed times, use duration or calendarDuration arrays. For more information on updating your code, see Version History or Replace Discouraged Instances of Serial Date Numbers and Date Strings.
