Multiple timezones for an Outlook ICS?

I have already visited this question Is There a Workaround for lack of Olsen TZ TZID Format in ICS File

I was able to understand why Outlook messes up with the times of two events in same timezone but in daylight save mode eg:

BEGIN:VCALENDAR
VERSION:2.0
PRODID: // Some staff
METHOD:PUBLISH
X-WR-CALNAME:Adak Events
BEGIN:VEVENT
UID:ev1
DTSTART;TZID=America/Adak:20140619T120000
DTEND;TZID=America/Adak:20140619T130000
DTSTAMP:20150409T105433Z
TRANSP:OPAQUE
X-MICROSOFT-CDO-BUSYSTATUS:BUSY
SUMMARY:Adak Event
LOCATION:Adak
DESCRIPTION: Summer
END:VEVENT
BEGIN:VEVENT
UID:ev2
DTSTART;TZID=America/Adak:20141219T120000
DTEND;TZID=America/Adak:20141219T130000
DTSTAMP:20150409T105433Z
TRANSP:OPAQUE
X-MICROSOFT-CDO-BUSYSTATUS:BUSY
SUMMARY:Adak Event
LOCATION:Adak
DESCRIPTION: Winter
END:VEVENT
END:VCALENDAR

But my real question what happens when I want to have multiple events in multiple timezones? I have seen that the solution to specify a timezone is:

BEGIN:VTIMEZONE
TZID:Europe/Prague
BEGIN:DAYLIGHT
DTSTART:20140330T030000
TZOFFSETFROM:+0100
TZOFFSETTO:+0200
RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=3
TZNAME:CEST
END:DAYLIGHT
BEGIN:STANDARD
DTSTART:20141026T020000
TZOFFSETFROM:+0200
TZOFFSETTO:+0100
RRULE:FREQ=YEARLY;BYDAY=-1SU;BYMONTH=10
TZNAME:CET
END:STANDARD
END:VTIMEZONE

But when I have multiple timezones in a single ICS? How can I handle such a thing for Outlook?

PS: In other mail apps TZID did the job so far

First, defining America/Adak Time Zone by olson database And 2 events are, so defining 2 Items x-WR-CALNAME:icsfilename:Solstice x-WR-CALDESC:Added with ics file but 2014 is too old so I change year setting 2014 > 2019 Summer and Winter solitude

BEGIN:VCALENDAR
RODID:-//Microsoft Corporation//Outlook 19.0 MIMEDIR//EN
VERSION:2.0
CALSCALE:GREGORIAN
x-WR-CALNAME:icsfilename
x-WR-CALDESC:Added ics file :icsfilename.ics
X-WR-TIMEZONE:America/Adak
METHOD:PUBLISH
BEGIN:VTIMEZONE
TZID:America/Adak
X-LIC-LOCATION:America/Adak
BEGIN:DAYLIGHT
TZOFFSETFROM:-1000
TZOFFSETTO:-0900
TZNAME:HST
DTSTART:19700308T020000
RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=2SU
END:DAYLIGHT
BEGIN:STANDARD
TZOFFSETFROM:-0900
TZOFFSETTO:-1000
TZNAME:HDT
DTSTART:19701101T020000
RRULE:FREQ=YEARLY;BYMONTH=11;BYDAY=1SU
END:STANDARD
END:VTIMEZONE
BEGIN:VEVENT

Yes, you can define multiple time zones. And dates in the VEVENT part can refer to these multiple time zones.
