HTML/PHP Timezone Feed Primer Tutorial

HTML/PHP Timezone Feed Primer Tutorial

Today we delve into timezone web applications using RSS feed data, in our case courtesy of Gomashup … thanks.

Maybe you are good with timezones, as you make a lot of International phone calls, and get used to it, but there are a lot of exceptions to the geographical (ie. longitudinal position) logic for several reasons like …

• daylight saving
• political decisions (especially around the International Date Line (180°E and 180°W) … ie. the opposite longitude to Greenwich (as of Greenwich Mean Time), which is at at 0°E and 0°W)

… plus we all know that “when you are having fun” … well, you know what we mean?!

So all those interruptions to the longitudinal way the time should be, in any given longitudinal place on Earth, needs to get a name, so the international convention gives a Region/PlaceIdentifier type of TimeZoneID, and so, even though we offer a finder of your TimeZoneID from our web application today, don’t count on finding it that way, because the places used as TimeZoneID PlaceIdentifiers are sometimes quite obscure, or at least to those “not in the know” I guess … but my favourite so far has been “America/Indiana/Tell_City”, as I hadn’t heard of Tell City before doing this web application … glad to meet you in code, Tell City, Indiana, USA.

Today’s work has that special treat of combining “Where” and “When” in its themes, and think you may find it interesting to try a live run, and or peruse the code as per …

• HTML/Javascript source code daylight_saving_time.html … supervising … but needing …
• PHP source code daylight_saving_time.php … because the recent “Client Pre-emptive Iframe” thoughts don’t work so well for the cross-domain requirements that Gomashup’s RSS feed presents to us

Thinking back on it, it stands to reason some aspects of “Where” are intertwined with “When” by where we live … doh!

Anyway, hope you enjoy thinking about time and space … and all that. It is a topic of huge interest to those people out there trying to Internationalize their websites.

If this was interesting you may be interested in this too.
