ICS imports in to Windows Outlook off by one hour

ICS files present an issue in some Windows versions of Outlook (event time is one hour off) that is avoided if the ICS file uses UTC time. This is because Windows apparently expects TZ names in another format.

An apparent workaround would be to convert times to UTC, but this also causes some oddities in other providers like macOS Outlook.

An alternative solution would be to have a separate export specifically for Outlook that uses TZ formats Windows will recognize.

    As stated in comment #5, there are several issues on the spatie/calendar-links Github page that relate to this issue.

    There is a new issue on the Github page that is now merged and solves the Github issues in: #73, #119 and #140.

    The issue itself states:

    This PR intends to fix Daylight Savings Time issues reported in #119 and #73.
    This code originated in PR #140 (thanks @kodie) and was rerolled so that it now applies cleanly to version 1.8

    I can confirm after testing that the issue with ICS import being off by 1 hour are now gone with this fix merged.

    This would render the patch provided in #7 in this issue queue obsolete since the problem is now solved upstream in the spatie/calendar-links library. I will leave this issue set to "needs review" because committing the patch seems no longer needed. Maybe someone else can test and set this issue to "fixed"?
