Actually, it WAS twenty-five or -six to four," referring to the time, which was either 3:35 or 3:34 (am). So yes, it was apparent that Robert Lamm (the songwriter) DIDN'T really know what time it was (at least not exactly).
But the second line of Chicago's other song (mentioned here) was "Does anybody really care?"
Since Robert Lamm apparently couldn't be bothered to determine the exact time--he was essentially saying, "Within a minute, that's close enough"--obviously the answer to the question about caring was "Not all that much..."
