Date and Time Difference tool counts wrong difference and wrong date format

Problem:
I checked date difference and date format in Utility - Date and Time Difference example of Warewolf where I found it calculated wrong difference and also date format was not correct.

Warewolf Version I am using is 2.8.1.3

Current Date: 3rd July 2023
Date Format passed in example is: yyyy/mm/dd 12h:min:ss am/pm
New date should be like 2023/07/03 but in example it was resulted 2023/03/07.

Date Difference:
