Server-side resolution of {{current_date}} and {{current_datetime}} for
agent instructions used the server's timezone, so agents received UTC
instead of the user's local time the variables are documented to provide.
The browser's IANA timezone is now sent with each request and threaded
through replaceSpecialVars, anchoring those variables to the user's local
wall clock. {{iso_datetime}} stays UTC. Invalid or missing zones fall back
to the previous behavior.
