You can get just part of the date, for example:

var d = new Date;

// this string will change once a day for the same user
var rnd_str_day = d.getFullYear() + '_' + d.getMonth() + '_' + d.getDay();
href= 'http://example.com/style.css?' + rnd_str_day;

// this string will change once an hour
var rnd_str_hour = d.getFullYear() + '_' + d.getMonth() + '_' + d.getDay() + '_' + d.getHours();
href= 'http://example.com/style.css?' + rnd_str_hour;

And so the css will be uncached once a day or an hour, depending on your requeriments.
