Closed Issue: Better readability with extension methods on int [10087]

Include Minutes(), Hours() and Days() extension methods on integers, for better readability of DateTime assertions.
For example:

public static TimeSpan Minutes(this int source)
{
return TimeSpan.FromMinutes(source);
}

This allows assertions like:

theDateTime.Should().BeLessThan(10.Minutes().Before(otherDateTime));
