Adding a day label with your month when your interval unit are days.
1. Edit \scripts\l10n\tr\labellers.js file, add:
    Timeline.GregorianDateLabeller.dayNames["tr"] = ["Pt", "Sa", "Ça", "Pe", "Cu", "Ct", "Pa"];
2. Edit \scripts\labellers.js file, under getMonthName function add this function:
    Timeline.GregorianDateLabeller.getDayName = function(day, locale){return Timeline.GregorianDateLabeller.dayNames[locale][day];}
3. find the defaultLabelInterval function in the labellers.js, modify the Timeline.DateTime.DAY case in the switch to the following:
    text = Timeline.GregorianDateLabeller.getDayName( date.getDay() , this._locale) + ", " + Timeline.GregorianDateLabeller.getMonthName(date.getUTCMonth(), this._locale) + " " + date.getUTCDate();
