ISO8601 date/times

Dear all,

I built some ISO8601 date/time classes, and some initial test cases. If 
anyone wants to use this material for Gobo, you are welcome. The classes 
are directly visible here:

http://my.openehr.org/wsvn/ref_impl_eiffel/TRUNK/libraries/common_libs/src/date_time/?rev=0&sc=0

Also, there are lexer patterns visible in 
http://my.openehr.org/wsvn/ref_impl_eiffel/TRUNK/libraries/common_libs/src/structures/syntax/dadl/parser/dadl_scanner.l?op=file&rev=0&sc=0

I took the idea of cached results of validation routines from (I think) 
Colin's code that I found in gobo34 release. The code is not by any 
means beautiful, and I am not generally into hand-built parsers, but it 
seemed a better way for this than the usual gelex/geyacc approach....

If you want to download the code and run the tests, check out the 
subversion repository TRUNK - see instructions at 
http://svn.openehr.org/ref_impl_eiffel/TRUNK/project_page.htm . Note the 
developer instructions down the page. Currently this will probably only 
work out of the box on Windows, but I think only new Ace files should be 
needed for the Mac and Linux.

If you don't want to use Subversion, you can probably just pull the tgz 
of the TRUNK visible at http://my.openehr.org/wsvn/ref_impl_eiffel/?sc=0 
- haven't tried this but I don't see why it wouldn't work. You will 
still need to set an OPENEHR environment variable.

To run the tests, the test application is in the path 
$OPENEHR\ref_impl_eiffel\libraries\common_libs\test\app ; the date/time 
tests are the 6th set of tests. Yes, I know, the testing framework is 
archaic....Peter Gummer is getting me up to speed on all the nicer ones 
out there, and we will incorporate them when we have a chance...
