The day headers in timeline view are part of the TimeRulerItemStyleSelector. So are the minor and major ticks. And so are the vertical lines. There are no borders corresponding only to the day headers, however.
To create vertical lines that can have a different brush for the days only, you need a custom TimeRulerItemStyleSelector.
In that selector you can get the datetime data that comes with each vertical line, and provide a custom style for the timeruler line when the line marks the start of a day - i.e. 12:00 AM.
Such a selector would look something like this:
item, DependencyObject container, ViewDefinitionBase activeViewDeifinition)
TickData tick = item
(tick.DateTime == tick.DateTime.Date)
.SelectStyle(item, container, activeViewDeifinition);
You will also need to customize the day headers themselves to match the style applied to the vertical lines. The style to do that is TimeRulerGroupItemStyle
, which is a part of the TimeRulerItemStyleSelector.

related to customizing the time ruler items.
I hope this helps.
