I have created a Powershell/XAML app, that on button press makes a RESTAPI call, parses the JSON response into fields in the app front end. All fine so far.
These fields will be populated with a string representing a time, so “1800” or “2000” etc.
The user can then change this from 1800 to 1900 for example.
This is all fine, and in the background the app will use 1900 to update a setting to be used in a POST back.
However there are other settings that are offset by 90 mins of the time above. I don’t want the user to have update each one, which is why I am trying to programmatically.
But try as I might, I cannot take a string of 1800, add 90 mins to it and make the value 1930 (not 1890).
