 In connection with and as a result of our work on time use, we established the Research Network on Time Use (RNTU) in cooperation with the Federal Statistical Office and with the support of the Federal Ministry of Education and Research (BMBF). The aim of this project is to promote and intensify international cooperation on this topic. This project is realized on the Internet. A special feature is the Research-Safe, which gives an overview of who, what, when, where, with what etc. has worked on this research area on the basis of a questionnaire. With this research safe, an internet-based database query can be made via a relative database system. During the reporting period, RNTU was continuously updated and expanded with current international publications and other information on the use of time. Work on the complete redesign of the RNTU homepage with extended functions from the previous reporting period was to be continued. Following the above-mentioned start-up financing, RNTU is now operated from its own resources
