+ * fields for editing the date and time. When the user submits the form, the
+ * results can be fed back into the second function, which turns it back into
+ * an icaltimetype. The "prefix" string required by both functions is prepended
+ * to all field names. This allows a form to contain more than one date/time
+ * property (for example, a start and end time) by ensuring the field names are
+ * unique within the form.
+ *
+ * NOTE: These functions assume that the icaltimetype being edited is in UTC, and
+ * will convert to/from local time for editing. "local" in this case is assumed
+ * to be the time zone in which the WebCit server is running. A future improvement
+ * might be to allow the user to specify his/her timezone.
