A time bank is a bank of hours! The people exchange services and get payed back by time(hours). All i need is to make a calendar and a list of people! anyone puts his availability in the calendar and someone else can book that person! On the other hand he can accept or refuse! After that the person accepted ho gave the service has 1 hour more in his account, who recieved the service has one hour less in his account...

Do you think that is possible with Artio?
