Now 5pm tasks can be viewed in calendar software like Apple iCal, Google Calendar, Mozilla Sunbird and any other calendar that supports iCalendar format. You can view all the tasks, just the ones you are attached to (are a part of the Task Team) or just the tasks from a particular project. Tasks can be imported into the calendar as tasks (“to do items” in Apple iCal) or events. Read more about it here.
