QreportTimeParser

A Time/Date parser with implicit precision.

Installation

Add this line to your application's Gemfile:

gem 'qreport_time_parser'

And then execute:

$ bundle

Or install it yourself as:

$ gem install qreport_time_parser

Usage

Qreport::TimeParser will parse human-specified Time values into Time ranges with implicit precision.

Examples

require 'qreport/time_parser'

p = Qreport::TimeParser.new
p.now = Time.parse('2011-03-10T15:10:37-06:00')

puts p.parse("now").to_TimeRange
