Please help fix this Calender bug

I reported this bug before, but got no response. Its starting to really annoy me now. I changed my time to Australian time as that is where I live. When I did this, the stories did not link to the correct calendar month. This is also true for the site.monthlist macro but I suspect its the same problem. For example, October is displayed as the month but the links are to September's stories, the next month is "october" eventhough this month is October. See it at my site
