The moment JavaScript library is really very useful and easy to use:

var parsedServerOutTime = moment(serverOutTime, "HH:mm:ss");
var parsedServerInTime = moment(serverInTime, "HH:mm:ss");

var milliseconds= parsedServerOutTime.diff(parsedServerInTime) //default milliseconds
var days = moment.duration(parsedServerOutTime .diff(parsedServerInTime )).asDays();// For days

asWeeks(); asMonths(); asYears(); etc etc for more details check http://momentjs.com/docs/
