Did anybody notice that the interval of second in Python datetime is [00,61] see the table on this page. https://docs.python.org/3/library/time.html#time.strftime
Why?

time() The time() function returns the number of seconds passed since epoch. For Unix system, January 1, 1970, 00:00:00 at UTC is epoch (the point where time begins).
Use the timedelta() class from the datetime module to add seconds to datetime, e.g. result = dt + timedelta(seconds=24) .
Use the time. time() function to get the current time in seconds since the epoch as a floating-point number. This method returns the current timestamp in a floating-point number that represents the number of seconds since Jan 1, 1970, 00:00:00. It returns the current time in seconds.
The answer is on the same page in footnote (2):
The range really is 0 to 61; value 60 is valid in timestamps representing leap seconds and value 61 is supported for historical reasons.
The "historical reasons" are described in https://bugs.python.org/issue2568.

There is no such thing as a double leap second. There cannot be 62 seconds in a minute. 59, yes. 60, yes. 61, yes. 62, no.
