Expected Behavior

DateAsText uses CultureInfo.InvariantCulture by default, if no other format provider is given.

Actual Behavior

DateAsText uses CultureInfo.CurrentCulture by default, if no other format provider is given. This is inconsistent with other classes such as DateOf, NumberOf and TextOf, which all use CultureInfo.InvariantCulture.

Mention any other details that might be useful

Also, there is only one constructor that lets us specify a different format provider:

public DateAsText(IScalar<DateTime> date, IText format, IFormatProvider provider)

This is inconvenient in a lot of situations, because the date needs to be wrapped in an IScalar and the format needs to be wrapped in an IText. Maybe we should add these ctors:

public DateAsText(DateTime date, string format, IFormatProvider provider)
public DateAsText(DateTime date, IFormatProvider provider)
