- * The display_icaltimetype_as_webform() and icaltime_from_webform() functions
- * handle the display and editing of date/time properties in web pages. The
- * first one converts an icaltimetype into valid HTML markup -- a series of form
- * 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.
