Since no one seemed to be using <code>NSDateComponents</code>, I thought I would pitch one in...
In this version, no <code>NSDateFormatter</code> is used, hence no string parsing, and <code>NSDate</code> is not used to represent time outside of GMT (UTC). The original <code>NSDate</code> is in the variable <code>i_date</code>.

<pre><code>NSCalendar *anotherCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:i_anotherCalendar];
anotherCalendar.timeZone = [NSTimeZone timeZoneWithName:i_anotherTimeZone];

NSDateComponents *anotherComponents = [anotherCalendar components:(NSCalendarUnitEra | NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond | NSCalendarUnitNanosecond) fromDate:i_date];

// The following is just for checking 
anotherComponents.calendar = anotherCalendar; // anotherComponents.date is nil without this
NSDate *anotherDate = anotherComponents.date;
</code></pre>

<code>i_anotherCalendar</code> could be <code>NSCalendarIdentifierGregorian</code> or any other calendar.
The <code>NSString</code> allowed for <code>i_anotherTimeZone</code> can be acquired with <code>[NSTimeZone knownTimeZoneNames]</code>, but <code>anotherCalendar.timeZone</code> could be <code>[NSTimeZone defaultTimeZone]</code> or <code>[NSTimeZone localTimeZone]</code> or <code>[NSTimeZone systemTimeZone]</code> altogether.

It is actually <code>anotherComponents</code> holding the time in the new time zone. You'll notice <code>anotherDate</code> is equal to <code>i_date</code>, because it holds time in GMT (UTC).
