Oops...meant this for the list, not just Daniel. --bs ---------- Forwarded message ---------- From: Bill Seymour <stdbill.h@pobox.com> Date: Wed, Nov 8, 2017 at 2:16 PM Subject: Howard Hinnant's tz Library (was Beginner's help request) To: Daniel Ford <dfnojunk@gmail.com> Yes, Howard's (exquisite in my opinion) library is specifically for C++, and is moving forward for inclusion in the ISO standard. (Indeed, a subgroup gave it unanimous consent just this morning.)

From http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0355r4.html:

"The implementation has been ported to Windows, Linux, Android, macOS and iOS." I've BCCd Howard in case he has anything more to say about it (although I wouldn't be surprised if he already follows this list anyway). --Bill Seymour On Wed, Nov 8, 2017 at 12:38 AM, Daniel Ford <dfnojunk@gmail.com> wrote:

Oops, looks like I was mistaken. Howard's library appears to be not (specifically) for Arduino, but a C++ library for Windows (and maybe other) platforms. Maybe it will compile in the Arduino IDE, though I suspect it will be problematic, if possible at all.

And I've so far found only one TZdb mirror that keeps a current copy of the data - very disappointing. It's a shame the whole TZdb scheme is so user-unfriendly. Quite discouraging.

Woohoo! I've discovered (and downloaded) an Arduino library, written by Howard E. Hinnant:

"This timezone library is a complete parser of the IANA timezone database. It provides for an easy way to access all of the data in this database, using the types from "date.h" and <chrono>. The IANA database also includes data on leap seconds, and this library provides utilities to compute with that information as well."

All I need to find now are established TZdb mirrors that keep their copy up-to-date, so I don't overload the master TZdb with queries. Can anyone point me to any, please?
