Local notifications not adjusting for timezones

Question

I\'m scheduling a local notification with an NSDate with the time set to 9pm and am setting the notification\'s timezone to UTC/GMT.

If I set the device timezone to UTC

Answer 1

This doesn't seem be the case for daylight savings change. I have some repeating notifications with the timezone set to the localTimeZone but since this last weekend when the clocks went forward an hour they are firing an hour later, ie at 19:00 instead of 18:00.

Seems like when I schedule an event I will have to determine the timezone for that date and use that.

Thanks

Answer 2

See the documentation of the timeZone property of UILocalNotification:

... If you assign a valid NSTimeZone object to this property, the fire date is interpreted as a wall-clock time that is automatically adjusted when there are changes in time zones; an example suitable for this case is an an alarm clock.

So I assume that if you want an absolute time for the notification, you must not assign a time zone.
