context is not used by this implementation.

String representations for dates as found in XAML value processing are based on the en-US culture. This is because XAML processing for culture-sensitive information is split conceptually between compile-time and run-time phases and must use a known string representation throughout. For more information, see WPF Globalization and Localization Overview.

The current implementation uses a format string that is adjusted depending on whether aspects of the supplied DateTime have values. For example, if there is no value in TotalSeconds, the format string is in the form yyyy-MM-dd rather than writing out full-verbosity zero values for the time component.
