Calendar time zone offset incorrect for ICS import

Question

I am subscribing to a Splunk On-Call (fka Victorops) calendar via the ICS URL they provide. Unfortunately, Confluence is assuming it's in UTC so it's adjusting for my local time zone. Is there a way that I can tell Confluence that it's EDT so it won't adjust it?

In this example, the handoff time is set for midnight but it is shifted back to 8pm. I'm assuming that's due to time zone offset.

@Jason Eckelstafer My understanding is that it looks at the timezone set on the Confluence instance and then matches that to what you are syncing with.  So if your confluence instance is set to a different time zone there would be a shift.  If it is the same as the ics file then no change should occur.

The timezone is being encoded in the ics file and my Confluent profile is also set to the correct EST timezone. Does the calendar use this information to properly shift events?

@Jason Eckelstafer Team calendars is going to read the ICS URL as it is provided.  Is there a way that you can include the encoding in the ICS URL?   You might also look at your Confluence profile's timezone to make sure it is set properly for your location.
