参数列表后的JS:SyntaxError:missing)

我在参数列表后出现以下错误:SyntaxError:missing)

功能:

function toTimestampArti(strDate, dk) 
{
        var birdk = 60000;
        var artidk = dk * birdk;
        var datum = Date.parse(strDate);
        var timeoff = new Date().getTimezoneOffset() * 60 * 1000 * -1;
        var time = datum + timeoff + artidk;
        return time;
}

运行代码:

toTimestampArti(strDate:06.01.2018 08:30:00, dk:10)
