;;; Commentary:
;; Tests that event-clamping (checking how long part of an event
;; overlaps another time span) works.
;;; Code:

:use-module (srfi srfi-88)
:use-module ((datetime) :select (date time datetime))
:use-module ((vcomponent datetime) :select (event-length/clamped))
:use-module ((vcomponent create) :select (vevent)))
(define ev
(vevent
dtstart: (datetime year: 2020 month: 3 day: 29 hour: 17)
dtend: (datetime year: 2020 month: 4 day: 1 hour: 10)))
;; |-----------------| test interval
;; |----------| event interval
