 time can be any string acceptable by http://www.php.net/strtotime, the
 template will output that time's month.

 If you don't want to pass in a date you can set time like this:
 {% set time = "now"|date("U") %}
 {% set time = "December 2012"|date("U") %}
 
 Data (in activityByDay) is collated by activityByDay[year][month][day], which holds a list
 of activity data for each day. YMMV for your own needs.
