Convert "dtStart"/"dtEnd" timezones of schedule to local timezone/timezone

[BarryCarlyon]

@Gewerd_Strauss

The issue I am having is that I simply do not know how to convert from Arbitrary TimezoneX to Arbitrary TimezoneY, or to the local timezone (without hardcoding it in, I mean, which while possible is not really a solution to this issue.)

Use a time parsing library for your programming language of choice.
Or since you are pulling the iCal feed, pass it into an iCal parsing library for your programming langauge of choice

Which is what any calendar system does (like google calendar) when you feed it the iCal URL.

DSTAMP is the time this iCal was generated. The Z specifies Zulu aka UTC

Start/endd
Decalres the Timezone, New York, and it’s 2022 11 17 Time 19:00:00 thru 23:00:00 (New York Time)

This is according to the iCal speficiation. So no, not a unix timestamp.
