Info about Time, GIS and other usable XML(DB) Services

Question

Based on Re: how to retrive World Server time in Sql here some thoughts about "TimeService the XMLDB Way".
This post for all who are in need of such a solution. If I have time I will also post the proper XMLTABLE alternative.
Probably there are better ways - Does anyone know better / useful web services? (that can be used with or called from XMLDB).
Cool XMLDB examples that can be used by others are appreciated.
...while thinking about it I would do it for instance via HTTPURITYPE (also based on UTL_HTP btw).
In "steps" (based on XMLDB functionality and http://www.nanonull.com/TimeService/TimeService.asmx)
SQL> set long 1000000
SQL> set pages 50000
SQL> select httpuritype('http://www.nanonull.com/TimeService/TimeService.asmx/getTimeZoneTime?timezone=CET').getClob()
  2  from dual;
HTTPURITYPE('HTTP://WWW.NANONULL.COM/TIMESERVICE/TIMESERVICE.ASMX/GETTIMEZONETIM
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://www.Nanonull.com/TimeService/">5:54 PM</string>

Table created.
