daysInMonth returns one more day (timezone issue)

Utils.daysInMonth returns one more day. Method is not aware of TimeZone). I expect that daysInMonth should return list with the Sunday as the first element but this method returned Saturday as the first day in the array.

I have the same issue, I think it would be better to separate the logic from days in week. I can submit a PR.

I created this issue a year ago. I don't think they will fix this soon...
