A simple Ruby natural language parser for date and time ranges. (For example, Mon-Fri 09:00-16:30, etc.) Returns a boolean result.
Several date and time ranges can be supplied with matching patterns being separated by a comma.
$ sudo gem sources -a http://gemcutter.org
$ sudo gem install chronic_between
>> s = 'Mon-Fri 9:00-16:30, Saturday, Sunday'
>> c = ChronicBetween.new(s)
>> DateTime.now
=> #<DateTime: 2011-03-26T16:54:40+00:00
>> c.within? DateTime.now
=> true
>> c.within? DateTime.parse("28-Mar-2011 14:33")
=> true
>> c.within? DateTime.parse("28-Mar-2011 08:33")
=> false
