Live chat bubbles read createdAt.hour/.minute directly, but server created_at (UTC, ISO-Z) was parsed without .toLocal() while optimistic sends used DateTime.now() (local). On any non-UTC device, your own messages showed local time and received/history messages showed UTC within the same conversation. Add .toLocal() at the history-load + incoming-WS parse sites in both apps so bubbles match the optimistic path and the transcript view. Session timer math was already tz-safe (Dart .difference uses absolute instants).
