Organizer/attendee timezones in emails

Editor assessment

The subject names the corrected data exactly: organizer and attendee timezones in emails, which identifies both the affected parties and the artifact. fix is the right type, and the absence of scope is tolerable because the subject itself localizes the change. No body or footer; at this size the subject carries the claim and the pull number gives provenance. Wording is compact. Understandable and honest.
