Errrr - isn't that the way everyone says it? Or is the other way just an Americanised thing?
I'm not so sure that the phonetic pronnunciation changes because of time, but more due to geographic location (which then, in turn, bastardises other regions) - as a physicist, I like a metre to be a metre, irrespective of its' geographic location nor its' existance in time, so I'd prefer the dictionary to be a standard (there should only be one dictionary - there's only one English, right? )
