In Google Sheets, I formatted the cells as time for minutes, seconds, and hundredths of a second. Both with the system's own selection options and manually with (mm:ss.000) and ([m]:ss.000) in all cases, the cell display format is correct, but during calculations it gives an error that the cell is text, not a number. And the formula does not work. I also checked all the ways that Gemini suggested, none of them worked!
