Location Tracker for Android and Google Sheet - with Date/Time Formula
Add a new line to a spreadsheet when you enter or exit a specified area. The Spreadsheet row will include formula to give you the date and time in the correct format for further analysis. This recipe is easy to reproduce with multiple locations all adding rows to the same spreadsheet, for better logging of your locations. (note: This will lead to you running out of rows on your sheets much quicker however).
