Google Sheets – Show Sum When Multiple Cells Selected

google sheets

If I select multiple cells in a Google Spreadsheet,
sum or count appears at the lowerright corner according to the data type.

Sum is shown for numbers, and count is shown for characters, dates or times.
But I'd like to see 'sum' for times. How can I change this setting?

I know I can do this using 'sum' function in a separate cell, but I would like to see this more conveniently.

That's not possible in Google Spreadsheets.

How are you planning on making the date summation? To return a date?
