CopyCat Rails’ Time Extensions

I’ve become a fan of Ruby’s simple syntax. My favorite thing is the ActiveSupport’s Numeric Time Extensions. I’m starting a library of useful extensions, and I’m going to be adding a number of shortcuts to mock these extensions.

For those of you that don’t want to follow the link, check out the syntax:

# equivalent to Time.now.advance(:months => 1)
  1.month.from_now

  # equivalent to Time.now.advance(:years => 2)
  2.years.from_now

  # equivalent to Time.now.advance(:months => 4, :years => 5)
  (4.months + 5.years).from_now

Here is what I’ve gotten so far (it only includes int for now):

public static class DateExtensionsThatMockRuby
    {
        /// <summary>
        /// Retrieve the number of ticks for x Days.
        /// <example>long ticks = 5.Days();</example>

        /// <returns>ticks</returns>
        public static long Days(this int i)
