For those who still want to change the date format to names; you can use the following code in main.js
_date = new Date(value.frontend_value[0] * 1000);
_month = new Array();
_month[0] = "Jan";
_month[1] = "Feb";
_month[2] = "Mar";
_month[3] = "Apr";
_month[4] = "May";
_month[5] = "Jun";
_month[6] = "Jul";
_month[7] = "Aug";
_month[8] = "Sep";
_month[9] = "Oct";
_month[10] = "Nov";
_month[11] = "Dec";
_value = _month[_date.getMonth()] + ' ' + _date.getDate() + ', ' + _date.getFullYear();
Only downside about this is that you need to add is again after a component update.
