I guess like the guest right above, I don't see why there should ever be a problem. Stop watches are calibrated in minutes (2 places) - seconds (two places) - and often hundreths of seconds (2 places). The numbers 6, 7, 8, and 9 do't even appear in the left most column for each of the units. Read the watch and write it down. Times of 61 or 75 or 90 do not occur on a stop watch. "one-zero-five" is always 1:05 because there aren't three digits in the seconds column. "one-forty-seven" is always 1:47 My son ran track for years in high school and college, I went to lots of meets where events were timed. It was never and issue. Read the watch and write it down. If you have to add or subtract something for style, do it after the time is written down. Olympic equestrian events use the same principle, record the time and subtract penalty seconds for knocking over jumps etc.
