Subject: [PATCH 1/2] Use mktime instead of gmmaketime. On the 1st of every
 month the following options are generated:

<select id="filter_start_date_month" name="filter[start][date][month]">
<option value="1">Dec</option>
<option value="2">Jan</option>
<option value="3">Feb</option>
<option value="4">Mar</option>
<option value="5">Apr</option>
<option value="6" selected="selected">May</option>
<option value="7">Jun</option>
<option value="8">Jul</option>
<option value="9">Aug</option>
<option value="10">Sep</option>
<option value="11">Oct</option>
<option value="12">Nov</option>
</select>

I do not totally understand the problem but using mktime instead of gmmktime fixes the issue.
