I've never built with that particular combination, and you exposed a couple of typos. I reproduced the problem artificially on GNU/Linux by building with "make CFLAGS='-DHAVE_SETENV=0'" and installed the attached patches. This fix should appear in the next release, which should be soon.

Dear Paul, I'm Afaf EL MAAYATI from National Telecommunications Regulatory Agency in Morocco. Actually, in the current version of Time Zone Database (https://www.iana.org/time-zones) for Africa region, and especially for Morocco, it’s mentionned that a program will be running to implement the transition dates. According to this program, the next transition dates (during 2023) are as below : - March 19, 2023 (switching to GMT). - April 30, 2023 (switching back to GMT+1). In fact, we will switch back to GMT+1, advancing 60 minutes, on Sunday, April 23 at 2:00 a.m (not on April 30). Please refer to the official annoncement, published by the Ministry of Digital Transition and Administration Reform: https://www.mmsp.gov.ma/fr/actualites/passage-%C3%A0-l%E2%80%99heure-gmt-%C… So, would you please update the program, in order to consider « April 23 at 2:00 a.m » (for switching back to GMT+1). Thank you in advance for your feedback and for your habitual support. Thank you.

Maryland bill status
by Arthur David Olson March 21, 2023

March 21, 2023

Crossover day has come and gone in the Maryland state legislature; bills not passed by one of the two chambers by crossover face substantial hurdles in gaining approval. Neither the House-side nor the Senate-side bills shifting Maryland to permanent DST (with the potential for a short-notice shift) made it out of committee. Links to bill status below. My guess: the bill (it's actually the same bill, cross-filed) will be back next year.-( @dashdashado https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/hb0165?ys=2023rs https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/sb0268?ys=2023rs

Dears, This is to check if any package is available for Egypt (Africa/Cairo) with the below DST description. We couldn't find any on the web site, so we were also wondering about how to request a package. [cid:image001.png@01D957DC.84E5E1E0] BR, Mostafa Dahab
