# ActivityDefinition (activity-definitions/<id>.md). Schedules are fixed-time

incompatibility: >-
|
||
|
|
expected-rate cannot express a weekday-only schedule. A PT26H window
|
||
|
|
raises a false finding every Saturday, Sunday and Monday morning; a
|
||
|
|
window long enough to span the weekend (P4D) hides a three-day
|
||
|
|
outage midweek. Declared as reconciliation against local activation
|
||
|
|
records instead. Suggested change: allow an expected-rate entry to
|
||
|
|
name a calendar (e.g. a cron expression and timezone) so the window
|
||
|
|
is counted in scheduled slots rather than wall-clock time.
