Thanks for the heads-up about the bill. I found a copy on the Rada website[1]. Assuming the president signs it and it becomes law, we'll need a change and a new TZDB release. The bill says that the law would take effect three months after promulgation, so it'd be helpful to find out its promulgation date whenever that happens to be. A further proposed resolution was introduced today[2] to annul yesterday's decision and stick with the status quo, on the grounds that yesterday's decision wasn't properly conducted. Not knowing Ukrainian politics, I don't know how today's proposal will affect matters. I am attaching a draft TZDB patch but I haven't installed it into the development version, because the effective date isn't known (I approximated it as "2025" in the draft patch), the bill as it stands might not become law, and the patch will need commentary. The zonenow.tab part of the draft patch would be temporary and that file would need to be updated further after 2024-10-27 as Ukraine would merge with Libya and Kaliningrad for future timestamps.
