# Calculating elapsed time problems

I am new to LibreOffice. The formula to calculate the elapsed time works in Excel but it's not working in LibreOffice. I found this to try - https://help.libreoffice.org/Calc/Cal... and it worked when I inputted it on my windows PC Excel spreadsheet. So I used it on LO and the time difference I get from 10am to 6pm is .333. What am I doing wrong?
