Setting timezone as UTC creates strange behaviour

[pezza3434]

Hi there,

Thanks for a maintaining this great package, I've been using it for a few years. I've just upgraded to the latest version from 1.4.3.

Just a heads up, that setting the timezone to utc:

const cal = ical({ domain: "eventcalendarapp.com", name: calendarName, timezone: "UTC", method: "publish" });

Stops the DTStart and DTEnd dates from being created with a 'Z' at the end. Which if I understand correctly makes them floating times.

Removing the timezone solves the issue, and reading the readme and the code it seems if no timezone is stated then it is handled in UTC time. Just a bit strange behaviour.

Apologies for being lazy and not doing a pull request.

Thanks again for a great package.

Related to this, if you set UTC as a timezone for an event, the dates become 'TZID=UTC 2021blahblah'. I'm not sure if setting the TZID on an event to utc is ever valid based on this from the spec:

"This parameter MUST be specified on the "DTSTART",
"DTEND", "DUE", "EXDATE", and "RDATE" properties when either a
DATE-TIME or TIME value type is specified and when the value is
neither a UTC or a "floating" time."

I could be wrong, I haven't researched the issue in huge detail.

Currently UTC is the default and therefore does not need a call to timezone(). The call with timezone('UTC') currently causes incorrect output, I would now note this here as a bug. The correct call for UTC would be timezone(null) or no call at all.
