/**
 * Utility to serialize Date objects as ISO 8601 string format.
 *
 * Note: apparently a format with and without the hour:minute separator
 * are valid ISO 8601 dates.  Jackson only handles the version without
 * the separator and as UTC whereas Calendar produces it with the separator
 * and time zone.
 * 
 * Jackson: 2011-02-03T19:25:53.656+0000
 * Calendar: 2011-02-03T14:25:38.649-05:00
 * 
 * Prefer the Jackson version to make the XML consistent with the JSON representation.
