La tz database, aussi appelée la zoneinfo database, est une base de données qui contient différentes informations sur les fuseaux horaires du monde. Tenue à jour par plusieurs personnes, elle est surtout utile aux logiciels et aux systèmes d'exploitation[1]. Elle est parfois appelée la Olson database en l'honneur d'Arthur David Olson, son créateur[2]. En 2011, Paul Eggert est l'éditeur de la tz database[3]. Elle se distingue par sa convention de nommage, mis au point par Eggert, pour désigner les fuseaux horaires, par exemple « America/New_York » et « Europe/Paris »[4]. Cette base de données contient une grande quantité d'informations à propos des fuseaux horaires historiques, dont les anciens fuseaux et tous les changements apportés depuis 1970, début de l’epoch de l'heure UNIX[5] Elle tient compte des changements horaires, telle l'heure d’été et les secondes intercalaires[6]
Le 6 octobre 2011, suite à des poursuites judiciaires, la base est fermée. Le 14 octobre 2011, l'ICANN prend en charge l'hébergement de la base et s'engage à faire face à toutes les poursuites[7].
