  <p>This didn't affect me as a registered user because I had previously set my timezone to Eastern (New York) so the .ics files I uploaded above were in the correct (Eastern/New York) timezone. @justin-freeman-agileware and @kapn are not registered users in our system so they were given .ics files in Central time.</p>
  <p>This also explains why this problem was restricted to a limited number of our members, as many of our members were likely interacting with CiviEvent as registered users via tokens we sent them via email.</p>
  <p>So, to summarize, people interacting with our Civi install as unregistered users were downloading iCal invites with our default timezone, which was incorrectly set to Central/Chicago time.</p>

Answers.Text: And just for the record, it is your website / content management system (CMS) that sets the timezone. Not "Civi".
  
  CiviCRM reads the timezone information from the website. CiviCRM is not the Website, it's a different system which is connected to the website.

Answers.Body: <p>@valerie can you amend your question to include the correct timezone for your Event and also what timezone is set in your CMS? CiviCRM will use the CMS timezone when generating these files and if that's incorrect then the output will be incorrect also.</p>
  <p>It looks like you have since changed the CMS timezone because the current ICS results differ from your original question.</p>

Comments.Text: There is no attachment and the google link triggers a direct import that means I can't look at the code. However, I would suspect that looking at the ical invite would simply reveal that the timezone is set to Central. You'll need to check your CiviCRM or CMS settings for timezone information.

I think something has changed because your previous google calendar link definitely exhibited the behaviour you describe.

Title: CiviEvent iCal download for some users is in Central time when we expect it to be in Eastern time
ThreadText: # CiviEvent iCal download for some users is in Central time when we expect it to be in Eastern time
  
  (Asked by: username_0 on 2024-01-19)
  
  We're running CiviCRM 5.63.3 on Drupal. Our organization is in Florida which has both Eastern and Central time zones.
  
  I have a longstanding problem - some of our members will register for an event I have created for noon eastern time and when they download the .ics file the event displays in their calendar for noon Central time. The event is set up in Eastern time. Most of our members, including all the members who send me emails about this, are in Eastern time.
  
  Here is the [iCal file](https://drive.google.com/file/d/1N90BO0Gwk5-McebH5x6cyyHkWsGMrKMb/view?usp=sharing) and the [google calendar link](https://calendar.google.com/calendar/u/0/r/eventedit?text=Mid-Session+Briefing+2024&dates=20240126T120000/20240126T130000&details=+%0D%0A%0D%0AThe+60-day+Florida+Legislative+Sessions+began+January+9th.+Join+us+for+an+update+on+the+good+and+bad+bills+that+are+making+their+way+through+committees.+%0D%0A%0D%0AThis+presentation+will+be+recorded+and+available+later+in+case+you%26%2339;re+not+available+on+Friday+at+noon+EST.+%0D%0A%0D%0APlease+click+the+grey+%26%2339;Register+Now%26%2339;+button+below+to+register.+%0A%0A%3Ca+href%3D%22https://forms.fnps.org/civicrm/event/info?reset%3D1%26id%3D119%22%3EView+Lunch+and+Learn+Details%3C/a%3E&location=FL+%0D%09United+States%09&trp=false&sprop=website:https://forms.fnps.org/&ctz=America/New_York).

  Our Drupal installation was, unbeknownst to me, set to Central (Chicago) time.
  
  [![screenshot of our Drupal Regional Settings page](https://i.sstatic.net/znvoG.png)](https://i.sstatic.net/znvoG.png)
  
  This didn't affect me as a registered user because I had previously set my timezone to Eastern (New York) so the .ics files I uploaded above were in the correct (Eastern/New York) timezone. @username_3-freeman-username_3 and @username_1 are not registered users in our system so they were given .ics files in Central time.
  
  This also explains why this problem was restricted to a limited number of our members, as many of our members were likely interacting with CiviEvent as registered users via tokens we sent them via email.
  
  So, to summarize, people interacting with our Civi install as unregistered users were downloading iCal invites with our default timezone, which was incorrectly set to Central/Chicago time.

  It looks like you have since changed the CMS timezone because the current ICS results differ from your original question.
