Small gem to convert ruby Time, Date, and DateTime instances to Excel date integers. This is helpful when using some Excel parsers to compare the dates in the spreadsheet to dates you may be using elsewhere in the script.

Simple! Require the gem require 'to_xl', initialize a Time, Date or DateTime value. Call .to_xl on it.

irb(main):002:0> require 'to_xl'
=> true
irb(main):003:0> Time.now.to_xl
=> 42389
irb(main):004:0> Date.today.to_xl
=> 42389
irb(main):005:0> DateTime.now.to_xl
=> 42389

You can also convert a date integer or float taken from Excel into a Ruby Time object. Simply call from_excel
