Why do some calendar events shift in time when daylight saving time goes into effect? Recently the UK changed from winter time to summer time, I have noticed that the timing of some of my calendar appointments (Google Calendar via Google Sync) have also been shifted forwards by an hour, whereas some have not changed.

It could well be that the split is down to events created on the iPhone and those created on the Google Calendar web interface.

Does anyone know a work around for this, that will stop me turning up an hour early to things when the clocks change back in October?
You may be able to fix it by doing the following:


Open the Settings on your iPhone
Select "Mail, Contacts, Calendars"
Scroll down to the Calendars section
Select "Time Zone Support"
Turn on Time Zone support


Or maybe you want to turn time zone support off? It's a little confusing. Here's what Apple says:


  When Time Zone Support is on, Calendar displays event dates and times in the time zone set for your calendars. When Time Zone Support is off, Calendar displays events in the time zone of your current location.
