Month number 10 is when daylight saving ends. On the last Sunday, at 01:00 UTC, wallclock time changes from 03:00 to 02:00. This means October is one hour longer than it would normally be. If it's "October 1st 00:00" at the beginning of the month, then after 31 times 24 hours it is "October 31st 23:00". Try changing your x-axis label definition, especially the part "1:0:%b". I didn't try it, but I think you are placing labels at the wrong place and thus suffer from this "problem" (not really a problem, because if I'm right, you are asking RRDtool to do this).
