I was hoping that someone would have already pointed out that this is not quite correct phraseology, as the qualifier "old ways to" has to be inserted: e.g. "old ways to get time in GMT". The "new" ways have been around for nigh on 30 years in some cases, and aren't really "new" now. I've been using localtime_r() for almost that long, for example. Coming from another language, don't be fooled into thinking that what you are looking at in these lists is the current state of the art for the language.
