iCal data entered while offline is lost by iCloud

macuserinLA,

If I were in your situation I would set the sync preferences to "Manually."

Same thing just happened to me, using the latest Lion iCal syncing to iCloud: A couple hours worth of careful event rearranging (done while offline) disappeared without a trace.

Lots of googling turned up basically nothing on what could have gone wrong or how to avoid it. There are certainly many cases of iCal events mysteriously disappearing, often related to sync, and these seem to have existed through many old versions (e.g. since Leopard at least, and when syncing to MobileMe) in addition to the latest Lion/iCloud combination.

My wife missed some important appointments last year when this happened to her (on Snow Leopard/MobileMe). It is rather insane that something so important to people remains so unreliable.

Sorry I can't be of more help, but wanted to let you know you're not alone.

iCal is changing the dates and the times of events entered into it via MacBook. Shift one day forward with different start and finish times. Have checked all time settings on both devices and they appear correct.

Also, no syncing is taking place between iCloud and either iCal on phone or iCal on MacBook.

Can anyone help? Thanks.

Found the cause of the date discrepancy: on the 'home page' of the iCloud (where you see all the icons of mail, calendar etc). if you are signed in, your name will appear in top right corner. I clicked on that and made the change to the correct time zone. I have no idea why or how it switched to a time zone that I do not live in. Now the events entered are maintaining the date & time the way they were created.

I just had the same thing happen to me. All data entered offline completely lost?! Please advise.
