This is a limitation of the zip archive format itself. Because the old MS-DOS filesystem had a resolution of 2 seconds. the designers of the zip format decided that 5 bits were enough to store the seconds in a timestamp. So the stored value (a number between 0 and 31) is multiplied by two to get the actual number of seconds in the timestamp, and as a result all timestamps have an even number of seconds. May I close this bug?
