Yes:

Hi, Alessandro
Would it be worth noting somewhere, that these two implementations of
ISO8601 differ? Because I needed the DateTime::ATOM way to save the
timezone ... Even so the other one was also about ISO 8601 ...
My system is working towards a search-engine called ElasticSearch.
This one makes use of a Java method to format a date. This one is
defined here:
http://joda-time.sourceforge.net/api-release/org/joda/time/format/ISODateTimeFormat.html#dateOptionalTimeParser%28%29
The definition for a time-offset is defined like this:
offset = 'Z' | (('+' | '-') HH [':' mm [':' ss [('.' | ',') SSS]]])
Is there a format, you know of, that makes this difference (colon or
not) bullet-prove?
Bye,
Simon

This Q is possibly rather HTML (is there a good list for that...)
anyways;
Im in Sweden, and have done som pages with Swedish text, however our special
(weird) characters åäö
comes out wrong when displayd in browser, would be nice if I could tag the text
and keep the file as is rather
than changing the file format of the text (and encode the characters with some
double/prefix notation,
which I guess would be the main stream
anyone ?
regards
Georg

Save PHP script as UTF8, and make sure you output UTF8 headers

I have a working project using the above resources, though these are on a
Windows Server 2008 trial installation on a virtual machine in VMWare.
Is there an easy way to transfer the whole project to a legit Windows
Server 2008? So far I have the following backed up:
administration.config
applicationHost.config
redirection.config
Arachnophilia folder
MySQL folder
php folder
phpdebug folder
wwwroot folder
Thanks in advance.
