I'm forwarding this message from Martin Doug, who is not on the time zone mailing list. Those of you who are on the time zone mailing list should direct replies appropriately. --ado From: Martin Dong [mailto:cppcraze@gmail.com] Sent: Monday, July 30, 2007 5:22 To: markus.icu@gmail.com; yoshito_umaoka@us.ibm.com Cc: tz@lecserver.nci.nih.gov Subject: Re: FW: How to support such capabilites based on current Olson Time Zone implementation Dear Markus and Yoshito,   Thanks for leading me to ICU project, which is really a full-featured library for internationalization. I feel it's more appropriate to consider using it from the very initial system design. However our system has already had its own internationalization mechanism, now we only want to utilize Olson Time Zone database. We need a light-weight solution but I think ICU is too heavy for us.   Actually tzcode is a light-weight implementation, if I can make some change based on it to support what I want, I think it's enough.   Dear Olson,   I want to know more about tzfile in binary form. Is there any other detailed description? I feel it's a little bit hard to get it understood just through the tzcode (because the comments are vrey few:-).   Btw, for now can any new functionality be added into tzcode implementation? Or another question, if my change can meet my requirements and it goes into our system, does it need to go into Olson tzcode?   Sincerely, -Martin   On 7/28/07, yoshito_umaoka@us.ibm.com <yoshito_umaoka@us.ibm.com > wrote: For the second requirement "getting the next nearest DST transition time", next version of ICU (ICU 3.8) will provide the API. -Yoshito "Markus Scherer" <markus.icu@gmail.com> wrote on 07/27/2007 02:38:00 PM:

Dear Martin,

For at least the first requirement, you might want to try other time zone support libraries listed on this list's homepage [1], for example ICU [2]. You could also send an email to the icu-support mailing list [3] to see if your second can be provided for.
