The ics file we generate follows the iCalendar spec. Specifically, for Time, we generate UTC timestamps (source code 1, source code 2) suffixed with Z which adhere to the following:
FORM #2: UTC TIME
UTC time, or absolute time, is identified by a LATIN CAPITAL
LETTER Z suffix character, the UTC designator, appended to the
time value. For example, the following represents 07:00 AM UTC:
070000Z
The "TZID" property parameter MUST NOT be applied to TIME
properties whose time values are specified in UTC.
The other properties X-WR-TIMEZONE and X-LIC-LOCATION are not part of that spec.
Following on from that original topic in the OP, I see that others have noted in a related topic that this problem is specific to godaddy’s calendar view. Perhaps it’s a problem with how it’s being handled in their adapter when importing ical files. Have you noticed this issue with other calendars?
