#7 Output file requires DTSTAMP attribute else Outlook aborts

[Anonymous]

Outlook reports the error "Cannot import vCalendar file"
on any text/calendar content that is missing the
attribute "DTSTAMP" - for example :-

DTSTAMP:20050520T170604Z

Here's some ytnef output that won't work in Outlook:-
