Chrono
Chrono ist ein JavaScript-Parser für Datumsangaben in natürlicher Sprache, der unstrukturierten Text und relative Datumsangaben in strukturierte Datumsobjekte konvertiert. Er fungiert als Multi-Locale-Datumsparser und Expressions-Engine, die darauf ausgelegt ist, Zeitangaben global aufzulösen.
Die Bibliothek ist anpassbar und erlaubt die Definition benutzerdefinierter Regex-Muster und Verfeinerungsregeln, um geschäftsspezifische Datumsformate zu extrahieren. Sie bietet Mechanismen, um relative Begriffe wie „morgen“ oder „nächsten Freitag“ basierend auf einem spezifischen Referenzdatum aufzulösen.
Das System deckt internationale Datumsformatierung über verschiedene regionale Locales hinweg ab und bietet Timezone-Offset-Mapping, um Abkürzungen spezifischen Offsets zuzuordnen. Es umfasst Funktionen für die Extraktion natürlicher Sprache und die Auflösung relativer Datumsangaben.
