class MultiDateMatcher extends AnnotatorModel[MultiDateMatcher] with HasSimpleAnnotate[MultiDateMatcher] with DateMatcherUtils
Matches standard date formats into a provided format.
Reads the following kind of dates:
"1978-01-28", "1984/04/02,1/02/1980", "2/28/79", "The 31st of April in the year 2008", "Fri, 21 Nov 1997", "Jan 21, ‘97", "Sun", "Nov 21", "jan 1st", "next thursday", "last wednesday", "today", "tomorrow", "yesterday", "next week", "next month", "next year", "day after", "the day before", "0600h", "06:00 hours", "6pm", "5:30 a.m.", "at 5", "12:59", "23:59", "1988/11/23 6pm", "next week at 7.30", "5 am tomorrow"
For example "The 31st of April in the year 2008" will be converted into 2008/04/31.
For extended examples of usage, see the Examples and the MultiDateMatcherTestSpec.
