time-trade is a local exchange and trading system (LETS) consisting of people who share their services, knowledge, skills or objects.

The aim of time-trade is to create bonds between people in the Biel-Seeland region, to strengthen solidarity and trust, and to value the skills of all.

The network works without money. The unit of exchange is time. The hours, positive or negative, are registered on a personal account. All services have the same value. The loan of material is counted in hours, but never more than 3 hours per day.
