Charset for Digest Emails
by Owen Leibman Feb. 24, 2023

Feb. 24, 2023

I have been subscribed to the “tz digest”, which comes out about once a day. Whenever a non-ASCII character is part of the message, it is rendered as multiple question marks. This seems to be because the message is sent with a header: Content-Type: text/plain; charset="us-ascii" This is only a minor nuisance. However, as an experiment, I changed my subscription to receive the messages directly rather than in digest form. A message today used an emoji outside the ASCII range, and it was rendered exactly as intended. It came with the following header: Content-Type: text/plain; charset="UTF-8"; format=flowed Is there a setting that could/should be changed so that the digest is sent with the same header?

Austin Group POSIX TZ changes and Time Zone Taxonomy
by Brian Inglis Feb. 23, 2023

Feb. 23, 2023

Hi folks, Saw that the Austin Group is proposing to support *some* time zones in POSIX issue 8; see: https://www.austingroupbugs.net/view.php?id=1619 TZ=Area/Location Some of the zones could be categorized as they have proposed, but that uses terminology that I don't think we would approve of, leaves a lot of zones in the tzdb unsupported and unaddressed, and omits a whole reality which I have attempted to categorize in the attached. Perhaps some here would like to come up with better facts, names, terminology, and wording, and propose an update to the Austin Group, that better reflects what exists, and what they are meant to be standardizing? If they are going to standardize this, they should either do it properly, or drop it entirely, maintaining the status quo, as they are not going to be helping with their inaccurate terminology, and limited support! -- Take care.

Sorry, I didn't see this private email until now. Please try the attached patch, which I installed into the development repository. It fixes a portability bug present since TZDB release 2022f. As mentioned in <https://mm.icann.org/pipermail/tz/2022-December/032399.html> I'm planning to phase out support for C89, as these old compilers are not much used nowadays and the cost of maintaining the ports to these compilers is starting to outweigh the benefit. In the next release if you still need support for old compilers the plan is that you'll need to compile with -DPORT_TO_C89 and/or -DSUPPORT_C99. This is intended to be a heads-up for builders on obsolete platforms.

Hello: Maybe it's wrong to calculate local time by using the latest version tzdada2022g when zoneid is "America/Ojinaga". Thanks

Looking for details on timezones “right/…”
by Jens Tröger Jan. 30, 2023

Jan. 30, 2023

Hello, Today I stumbled upon timezone strings like “right/UTC”, “right/America/Jujuy”, and so forth, but I’m unable to find details on the meaning & classification of the “right/” here and how it relates to actual UTC and other timezones. I’d appreciate pointers or clarifications. Thank you kindly, Jens -- Jens Tröger https://savage.light-speed.de/
