The 2025b release of the tz code and data is available. This release contains the following changes: Briefly: New zone for Aysén Region in Chile which moves from -04/-03 to -03. Changes to future timestamps Chile's Aysén Region moves from -04/-03 to -03 year-round, joining Magallanes Region. The region will not change its clocks on 2025-04-05 at 24:00, diverging from America/Santiago and creating a new zone America/Coyhaique. (Thanks to Yonathan Dossow.) Model this as a change to standard offset effective 2025-03-20. Changes to past timestamps Iran switched from +04 to +0330 on 1978-11-10 at 24:00, not at year end. (Thanks to Roozbeh Pournader.) Changes to code 'zic -l TIMEZONE -d . -l /some/other/file/system' no longer attempts to create an incorrect symlink, and no longer has a read buffer underflow. (Problem reported by Evgeniy Gorbanev.)
