English: Golden clock symbol for GSSAs (Global Standard Stratigraphic Ages) that define the boundaries of almost all Precambrian units.
Deutsch: Symbol einer goldenen Uhr. Es wird in chronostratigraphischen Tabellen für Einheitengrenzen verwendet, die ein festgelegtes absolutes Alter (Global Standard Stratigraphic Age, abgekürzt GSSA) haben, statt durch einen GSSP unabhängig von absoluten Zeitwerten definiert zu sein (Anwendung ausschließlich im Präkambrium).
