Calzone

Outlook calendar showing wrong timezone in Google Calendar?

Outlook ICS feeds use Windows timezone names like "Romance Standard Time" that Google Calendar doesn't recognize — defaulting to UTC and shifting your events hours off. Calzone is a live proxy that converts them to standard IANA timezones automatically, keeping your calendar in sync with the correct times.
