Code snippet for adding certain number of hours to a date based on Priority & excluding weekends?

[Karen Woodmansee]

We are using Jira Cloud with the JMWE plug-in.  There is a great example for adding a certain number of days to a date excluding weekends on the innovalog site (https://innovalog.atlassian.net/wiki/spaces/JMWE/pages/156073991/Add+a+certain+number+of+days+to+a+date+excluding+the+weekends).

Does anyone have a code snippet example that can be used for adding a certain number of hours to a date based on Priority and excluding weekends?

P1: Due date = 12 hours

P2: Due date = 24 hours

P3: Due date = 36 hours

P4: Due date = 48 hours
