Kevin, I'm not saying that your package is not helpful. I'm just voicing my feelings about it becoming adopted as a .Net standard for the Olson TZ information. Other's have provided solutions, and though difficult to find, they are out there. Now, admittedly, I do prefer to insall classes that have pretty much a similar functions as opposed to those that incororate extra features. I do that mainly to better track what I've loaded without a lot of hassle. The naming convention follows suit. It may be silly, but there it is. I don't think I'm alone in those distinctions or reservations. I do have contact with the .Net world, being part a large web application community, and this particular issue is still not resolved in that application for those very reasons. I've followed this .Net integration topic for some while and have had many discussions with folks over the last few years about it. I know that we can all agree on this issue: Microsoft needs to support the TZ information rather than continue down their registry Timezones method. So, with that in mind, I would propose, and hope to see a link to your offering, and links to similar offerings appear as references. I do not favor any O/S over another at this point, they all have issues. But, in this area of timezone integration, I think the UNIX/Linux world gets the nod. Let folks decide for themselves what serves them best, and it's better to offer the information than not. I spent many hours surfing the .Net looking for a solution before I finally came up with my own that works for me. The whole business really becomse a non-trivial task to overcome in the Microsoft world, especially when developing for web applications that use MS SQL. It's really a challenge to provide web apps, when so many hosting providers cannot standardize on basic timezone settings. Of course, it's all part of relying on MS to bear the task to standardize on a better method. Just my thoughts, and wanted to clear up my last post, which was not meant to discourage, though I can see I was not clear. I apologize to you. -----Original Message----- From: Kevin [mailto:hellosticky@gmail.com] Sent: Thursday, August 23, 2007 6:15 PM To: tz@lecserver.nci.nih.gov Subject: Re: C#/VB.NET PublicDomain Olson Time Zone Database Implementation That is a fair criticism, however in its defense, the added functionality in the package only adds a few hundred Kb to the size of the DLL, so I do not understand the claim that non-TZ related code "detracts from it's acceptance from a broad spectrum of .NET users." Have you queried a broad spectrum/sample of .NET users? The reason I think it is worth mentioning on the main page is that there is no alternative, other than what Microsoft provides (as you mention, the latest incarnation simply rounds a few edges, but makes no significant advancements). The sole reason why I created this package was because I could not find such a package. Being in my shoes before I created it, I would not care that it contained other code. Since all of the code is in the PublicDomain, it would also be trivial for me to take out the TZ related code (a few source files), and either build my own package or simply insert the code files into my existing project. However, as developer of the package, I will not create a separate packaging of PublicDomain just to advance such a "pure" implementation. I do not want to shatter code, and create intricate co-dependencies, which defeats the purpose of the package as a milieu of simple-to-use .NET code. As for the name of the package, well I can't disagree with you, but I don't think that it detract from the usefulness of propagating the olson database throughout the .NET. The net of my defense against the arguments of package size and naming is that fundamentally it solves a problem that exists today -- lack of olson database support in .NET. This severely impacts interoperability, correctness, and functionality. Thanks for the consideration On 8/23/07, Phillip Guerra <Phillip.Guerra@nkch.org> wrote:
When last I reviewed this package, it included a variety of librairies, not just the tz implementation. In my opinion, this detracts from it's acceptance from a broad spectrum of .Net users. There is alos criticism of the library name 'PublicDomain' as not being descriptive of the contents of the library.
Now, I've not used the library, but after my initial review, I would not be an adopter of this particular implementation. I'm not sure if it should be the .Net defacto implementation. However, in fairness to
the developer, it's a start for folks wondering about how to go about this tz integration in a .Net MS world. The lastest MS implementation
of timezone information builds upon the already flawed practice of storing information in the registry. Although, the data structures improved a bit, this implementation still leave a lot to be desired.

Hi,
I created a fully Public Domain .NET library which implements the Olson time zone database for .NET applications. The package is called PublicDomain and the source, binaries, and documentation are available
at http://www.codeplex.com/PublicDomain. Olson time zone database support is just one part of a larger package of various pieces of public domain code. The package was written from scratch in C# and includes an objectified form of the olson time zone database (because we all know how fun it is to analyze the raw, obfuscated data). I also
created a variety of unit and regression tests.
The implementation used to be quite experimental, but now it has gone through a bit of usage and appears to be getting quite solid. I also wrote an article on codeproject discussing a simple use case of using the package (http://www.codeproject.com/useritems/Using_time_zones_in_NET.asp).
I would appreciate it if you included a description of this package for those that use .NET, including C#, VB.NET, etc. on the Olson Time zone database home page (http://www.twinsun.com/tz/tz-link.htm) -- using some form of less verbose description than mine above :-).
Thanks! Kevin
