Getting rid of the display the end time in ikhal (which is always starting time +1h)

[bjce]

Hello

I inserted an appointment of the type:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//PIMUTILS.ORG//NONSGML khal / icalendar //EN
BEGIN:VTIMEZONE
TZID:Europe/Paris
BEGIN:STANDARD
TZNAME:CET
END:STANDARD
BEGIN:DAYLIGHT
END:DAYLIGHT
END:VTIMEZONE
BEGIN:VEVENT
SUMMARY:blablbla
DTSTART;TZID=Europe/Paris:20250116T220000
DTSTAMP:20241110T180850Z
UID:999999999999999999999999999999999999
END:VEVENT
END:VCALENDAR

Although there is no endtime, ikhal keeps displaying the end time (corresponding to the starting time +1h). How to get rid of the endtime

[WhyNotHugo]

From https://www.rfc-editor.org/rfc/rfc5545#section-3.6.1:

For cases where a "VEVENT" calendar component specifies a "DTSTART" property
with a DATE-TIME value type but no "DTEND" property, the event ends on the same
calendar date and time of day specified by the "DTSTART" property.

It sounds to me like we should default this case to 0h, not 1h.
