to support the new time parser and search functions in YaCy a high precision detection of date and time on the day is necessary. That requires that the time zone of the document content and the time zone of the user, doing a search, is detected. The time zone of the search request is done automatically using the browsers time zone offset which is delivered to the search request automatically and invisible to the user. The time zone for the content of web pages cannot be detected automatically and must be an attribute of crawl starts. The advanced crawl start now provides an input field to set the time zone in minutes as an offset number. All parsers must get a time zone offset passed, so this required the change of the parser java api. A lot of other changes had been made which corrects the wrong handling of dates in YaCy which was to add a correction based on the time zone of the server. Now no correction is added and all dates in YaCy are UTC/GMT time zone, a normalized time zone for all peers.
