nsdate

I am trying to parse a date string from xml into an NSDate object in an iPhone app I am aware this must have been asked before, however, I believe I have the right syntax, but it is not working. Is there a problem with my code? The date string I need to parse is: 2011-01-21T12:26:47-05:00 The code I am using to parse it is: self.dateFormatter = [[NSDateFormatter alloc] init]; [self.dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]]; [self.dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"] autorelease]]; [self.dateFormatter setDateFormat:@"yyyy'

I am trying to achieve a dropBox sync and need to compare the dates of two files. One is on my dropBox account and one is on my iPhone. I came up with the following, but I get unexpected results.

Here we go: NSLog(@"dB...lastModified: %@", dbObject.lastModifiedDate); NSLog(@"iP...lastModified: %@", [self getDateOfLocalFile:@"NoteBook.txt"]); if ([dbObject lastModifiedDate] < [self getDateOfLocalFile:@"NoteBook.txt"]) {

I basically need to get current date and time separately, formatted as: 2009-04-26 11:06:54 The code below, from another question on the same topic, generates now: |2009-06-01 23:18:23 +0100| dateString: |Jun 01, 2009 23:18| parsed: |2009-06-01 23:18:00 +0100| This is almost what I'm looking for, but I want to separate the day and time. NSDateFormatter *format = [[NSDateFormatter alloc] init]; [format setDateFormat:@"MMM dd, yyyy HH:mm"]; NSDate *now = [[NSDate alloc] init]; NSString *dateString = [format stringFromDate:now]; NSDateFormatter *inFormat = [[NSDateFormatter alloc] init];
