Yeah, you're clearly right. Defining struct pg_tm's tm_mon differently
from the common understanding of struct tm's tm_mon may not have been
the greatest idea we ever had :-(. I dug through the uses of tm_mon in
the rest of ecpglib and didn't find any other similar mistakes, though.
Will fix, thanks for the report!
