What
Model deprecation dates are written as plain dates and read in Pacific time. To get the right offset, Claude Code used to ask the system's time zone data whether Los Angeles was on daylight saving time. It now works this out itself from the US rule: daylight saving runs from the second Sunday of March to the first Sunday of November.
Why
In normal cases the result is the same as before, so deprecation dates should land on the same moment.
