Duration?

Having a need for date-time arithmatic and timezone adjustments, the
new Duraiton and UCT conversion methods look like the ticket. Only
they are stubbed out. Is Duration available now, or should I do
something quick & dirty?

A couple of months ago, in a burst of enthusiasm, I implemented and verified
(with Richard Harmon's valuable assistance) some classes that implemented
the ANSI spec for DateAndTime and Duration.  Something else came up and I
have never got around to finishing off the job - mainly adding all the
ancillary classes and methods to do things like converting to/from String
and the existing Date/Time.

There are still some issues with my implementation (mainly to do with
TimeZone names which, I think, cannot be implemented in the way ANSI
defines) but I've uploaded the files to my web site anyway so that they are
available, as a starting point if nothing else, for anyone who wants them.

Seriously, it works well--recommended.

I meant to get back to Ian and ask if he intended to release it.

Ian, did I mention I added a couple of methods to convert to, from,
SYSTEMTIME?

An ancillary issue I think and only a minor limitation.

Terrific.  Thanks

Yessir.. Duration and an amazing collection of stuff your
http://www.iandb.org.uk/tweaks.htm ! Thanks, I'll pass along any work
I do on it.

It's good to see the Dolphin community producing goodies like the
VisualWorks.

Is there a central opensource collection like
http://www.sourceforge.net/ ?

Not that I recall, but it is some time since we corresponded on the subject
(my fault, sorry!!)  If you mail them to me I can include them in the
package - assuming that's OK with you.  The same goes for anyone else who
wants to contribute?

Not as such. However, Alain Fischer has made a good attempt at collecting
together links to all known Dolphin related pages, which is a good starting
point.

http://mypage.bluewin.ch/a.fischer/dolphinResource.html

I'm sure he will be interested in being told of any new links ...
