Hello everyone,

In my site I have a Webform which has two time fields as, Time-In and Time-Out.
Now in my webform results table I need a Total Hours field to show how many hours is in between time-in and time-out.

Which way do you think is the best and doable?

1-In views, I tried Global Math Expression, but I'm not sure if the built-in functions would allow me to have this expression?
2-I even tried Views PHP but I want to avoid it as much as possible since in the module page says so.
3-And the other way is to write a new view handler which I have no idea how to do it!

I did so many searches but couldn't find my answer, I would appreciate if someone can help me solve this issue.

Thank you in advance
