There's a preferred way of setting the duration

The representation uses the following literals:

P = denotes the duration and must precede every duration value

nY = the number prefix (n) is the duration in years

nM = the number prefix (n) is the duration in months

nD = the number prefix (n) is the duration in days

T = is the prefix for the time period in hours, minutes, and seconds. Not required if no times are defined

nH = the number prefix (n) is the duration in hours

nM = the number prefix (n) is the duration in minutes

nS = the number prefix (n) is the duration in seconds

As we need 9 hours of working time . Our string representation would be ""P0Y0M0DT9H0M0S"

where 9H shows 9 working hours.

Please use the below line to set duration

CctDuration duration = new CctDuration("P0Y0M0DT9H0M0S");
