I've done a conversion of the tzinfo datastore to use with MS .Net concentric apps. One of the issues encountered is the need to expand the info to hold discrete records for the years named for rules, and zones. For example, the number of rules created are over 4,500+. Properly indexed, I don't see an issue with the number of rules. However, I still need to test the approach with example apps and usage cases. The information is a simple ascii file, similar to tzinfo, and a parsing program could be used to create other forms of the data like xml or database info. I would think the xml file would be useful for that purpose or even the expanded raw file to use for whatever further processing was required. The need for me was to provide the info for use by web apps which may be limited by security issues to use a host's system information, which on MS systems has no capability for historical reference, limited to the current year, and is known to be be less accurate. Still not sure if this is the most efficient method to go about it, but I found nothing like it in my searching for a similar solution. Most MS solutions are using the registry info, which has the above mentioned issues, and therefore not optimum. -----Original Message----- From: Paul Schauble [mailto:Paul.Schauble@ticketmaster.com] Sent: Thursday, February 23, 2006 2:59 PM To: tz@lecserver.nci.nih.gov; tz@lecserver.nci.nih.gov Subject: RE: Web service time computer It might be better to maintain TZDATA in xml and have a translator back to the current format. ++PLS -----Original Message----- From: tz-request@elsie.nci.nih.gov [mailto:tz-request@elsie.nci.nih.gov] On Behalf Of Deborah Goldsmith Sent: Thursday, February 23, 2006 1:00 PM To: tz@lecserver.nci.nih.gov Subject: Re: Web service time computer On Feb 23, 2006, at 8:59 AM, Andy Lipscomb wrote:
I've actually been trying to use this data to implement time zone conversion in REALbasic, and one of the steps in doing so has proven to be rewriting the data files in XML. I could contribute that much to
the efforts.
Actually, the ICU team is very interested in getting this data in an XML form as well. One of the projects on my to-do list is to make a proposal for changes to zic that would optionally emit a (stable) XML version of the data. If someone else gets to this first I would be happy to help. Deborah Goldsmith Internationalization, Unicode liaison Apple Computer, Inc. goldsmit@apple.com
