20 * The display_icaltimetype_as_webform() and icaltime_from_webform() functions
21 * handle the display and editing of date/time properties in web pages. The
22 * first one converts an icaltimetype into valid HTML markup -- a series of form
23 * fields for editing the date and time. When the user submits the form, the
24 * results can be fed back into the second function, which turns it back into
25 * an icaltimetype. The "prefix" string required by both functions is prepended
26 * to all field names. This allows a form to contain more than one date/time
27 * property (for example, a start and end time) by ensuring the field names are
28 * unique within the form.
30 * NOTE: These functions assume that the icaltimetype being edited is in UTC, and
31 * will convert to/from local time for editing. "local" in this case is assumed
32 * to be the time zone in which the WebCit server is running. A future improvement
33 * might be to allow the user to specify his/her timezone.
