When generating a report that spans a long time, the timeline header for the "days" view includes the numeric day of the month along with the abbreviation of the day of the week. But there is no indication of what month or year that particular day is referring to. So while scrolling through the report, you cannot tell what month you are in. A simple solution would be to include the full datestamp as a title attribute of the full header cell. The title attribute of the div that contains the numeric day of the month is useless.
