#### Parameters

self | a GDataCalendarEvent |
where | a GDataGDWhere to add |

### gdata_calendar_event_get_times ()

    GList *

                                           GDataGDWhen **when);

Gets the first time period associated with the event, conveniently returning just its start and end times if required.

end_time | a gint64 for the end time, or `NULL`. | [out caller-allocates]

                                   GDataGDWhen *when);

Adds `when` to the event as a time period when the event happens, and increments its reference count.

Duplicate times will not be added to the list.

Note: `gdata_calendar_event_add_time()` and `gdata_calendar_event_set_recurrence()` are mutually exclusive, as the server doesn't support positive exceptions to recurrence rules. If recurrences are required, use `gdata_calendar_event_set_recurrence()`. Note that this means reminders cannot be set for the event, as they are only supported by GDataGDWhen. No checks are performed for these forbidden conditions, as to do so would break libgdata's API; if both a recurrence is set and a specific time is added, the server will return an error when the GDataCalendarEvent is inserted using `gdata_service_insert_entry()`.

#### Parameters

self | a GDataCalendarEvent |
when | a GDataGDWhen to add |

Since: 0.2.0

### gdata_calendar_event_get_recurrence ()

    const gchar *
    gdata_calendar_event_get_recurrence (GDataCalendarEvent *self);

Gets the “recurrence” property.

#### Parameters

                                         const gchar *recurrence);

Sets the “recurrence” property to the new recurrence, `recurrence` .

Set `recurrence` to `NULL` to unset the property in the event.

Note: `gdata_calendar_event_add_time()` and `gdata_calendar_event_set_recurrence()` are mutually exclusive. See the documentation for `gdata_calendar_event_add_time()` for details.

#### Parameters

self | a GDataCalendarEvent |
recurrence | a new event recurrence, or `NULL`. | [allow-none]

Since: 0.3.0

### gdata_calendar_event_get_original_event_details ()

                                    gchar **event_id,
                                    gchar **event_uri);

Gets details of the original event, if this event is an exception to a recurring event. The original event's ID and the URI of the event's XML are returned in `event_id` and `event_uri` , respectively.

If this event is not an exception to a recurring event, `event_id` and `event_uri` will be set to `NULL`. See `gdata_calendar_event_is_exception()` to determine more simply whether an event is an exception to a recurring event.

If both `event_id` and `event_uri` are `NULL`, this function is a no-op. Otherwise, they should both be freed with `g_free()`.

self | a GDataCalendarEvent |
event_id | return location for the original event's ID, or `NULL`. | [out callee-allocates][transfer full]
event_uri | return location for the original event's URI, or `NULL`. | [out callee-allocates][transfer full]

### gdata_calendar_event_is_exception ()
