140
141 Indicate whether the organiser of an event can be replaced and the nature of
142 any replacement:
143

145 present or even previously unknown, may become the
146 organiser
147
148 attendee any new organiser must be a previously-recognised
149 attendee
150
151 never forbid the replacement of an event's organiser
152
153 participating
154 -------------
155
156 Default: participate
157 Alternative: no
158
159 Indicate whether a recipient participates in the calendar system. Note that
160 participation by default occurs because the handler programs will be defined
161 in the mail system for recipients fulfilling certain criteria; other
162 recipients will be handled in other ways. Thus, initial non-participation must
163 be defined by initialising this setting to "no" for all eligible users, if
164 this is the general policy on initial calendar system participation.
165
166 permitted_times
167 ---------------
168
169 Default: (none)
170 Alternatives: (see below)
171
172 Define the time values at which events can be scheduled. In its simplest form,
173 this indicates the resolution of a calendar for a participant supporting this
174 setting, with the given minute values being those allowed for the start and
175 end of an event. This setting requires a value of one of the following forms:
176
177 <minute values>
178 <hour values>:<minute values>
179 <hour values>:<minute values>:<second values>
180
181 Each list of values is a comma-separated collection of permissible values for
182 the unit of time being constrained. Any unspecified list is taken to permit
183 all normally permissible values for that unit of time. For example:
184
185 0,15,30,45 every 15 minutes from the start of each hour
186 10,12,14,16:0,20,40 every 20 minutes from 10:00 until 16:40 inclusive
187 12::0,30 every 30 seconds from the start of each minute during
188 the period from 12:00:00 until 12:59:30 inclusive
189
190 The purpose of this setting is not necessarily to impose availability
191 constraints but instead to impose a "grid" to which event start and end points
192 shall be "locked".
193
194 The values are interpreted in the local time of the participant. Thus, a time
195 represented in UTC may have apparently inappropriate hour (and for some zones)
196 minute values that correspond to permitted values in this participant's own
197 time zone.
