问题
When I call
NSDate *now = [[NSDate alloc] init];
in order to get the current date and time, I check it with:
NSLog(@"Date now: %@", now);
the date outputted is one hour in the past.
2010-10-08 12:04:38.227 MiniBf[1326:207] Now: 2010-10-08 11:04:38 GMT
Is my time zone set incorrectly somewhere perhaps?
Thanks!
Michael
回答1:
Use NSDateFormatter to localize the date:
NSLog(@"%@",[NSDateFormatter localizedStringFromDate:[NSDate date] dateStyle:NSDateFormatterShortStyle timeStyle:NSDateFormatterShortStyle]);

I've seen that behavior on the DatePicker running on iOS 4.1 devices while on iOS 4.0 and previous it does not happen. I can't confirm it is actually the same bug.
But I suggest you check whether is related with the acknowledged by Apple bug regarding dates/summer time/4.1 by running that code on < 4.1. Then you will need to decide whether to hack a fix for that particular version/dates or wait for the next release of the SDK to fix it and not support 4.1 devices...
The bug I'm talking about I believe only happens while passing dates within the summer time period (2010: 28th March - 31st October)

Use NSDate *now = [NSDate date];
I am using it and giving me perfect result.

Maybe your timezone is wrong in your iPhone simulator. Press the home button, go to settings.app and correct it ;)
