NSDate - Convert Date to GMT

Question

I need the ability to convert an NSDate value to a GMT Date.

How can I go about converting an NSDate value to a GMT formatted NSDate value, independent of whatever date locale settings the iPhone device is using?

Answer 1

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    dateFormatter.dateFormat = @"yyyy-MM-dd'T'HH:mm";

    NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
    [dateFormatter setTimeZone:gmt];
    NSString *timeStamp = [dateFormatter stringFromDate:[NSDate date]];
    [dateFormatter release];
