Parse a date string: E.g.:
SugarCube::DateParser.parse_date
“There is a date in here tomorrow at 9:00 AM”
> 2013-02-20 09:00:00 -0800¶ ↑
# File lib/cocoa/sugarcube-nsdate/date_parser.rb, line 10 def parse_date(date_string) if result = iso8601(date_string) return result elsif result = sugarcube_detect(date_string).first return result.date end end

Parse a date string: E.g.:
SugarCube::DateParser.parse_date
“You have a meeting from 9:00 AM to 3:00 PM”
> 21600.0¶ ↑
Divide by 3600.0 to get number of hours duration.
# File lib/cocoa/sugarcube-nsdate/date_parser.rb, line 36 def parse_duration(date_string) result = sugarcube_detect(date_string).first result && result.send(:duration) end
parse_time_zone(date_string)

Parse time zone from date
SugarCube::DateParser.parse_date
“There is a date in here tomorrow at 9:00 AM EDT”
Caveat: This is implemented per Apple documentation. I've never really
seen it work.
# File lib/cocoa/sugarcube-nsdate/date_parser.rb, line 24 def parse_time_zone(date_string) result = sugarcube_detect(date_string).first result && result.timeZone end
