  * A note about currency dates.  The CLDR data provides data to the day,

- * of a day to represent that day.  Thus you must be careful when converting
- * these values to and from actual times.  For example, if you construct
- * a time representing 12 noon GMT, and query the currencies available at that
- * time, you will not return a currency whose last day of availablilty was on
- * that day, since the time you provided is after the start of the day.
