@@ -38,6 +38,7 @@ Docs: https://docs.openclaw.ai
 - Docs/IRC: fix five `json55` code-fence typos in the IRC channel examples so Mintlify applies JSON5 syntax highlighting correctly. (#50842) Thanks @Hollychou924.
 - Telegram/forum topics: recover `#General` topic `1` routing when Telegram omits forum metadata, including native commands, interactive callbacks, inbound message context, and fallback error replies. (#53699) thanks @huntharo
 - Discord/config types: add missing `autoArchiveDuration` to `DiscordGuildChannelConfig` so TypeScript config definitions match the existing schema and runtime support. (#43427) Thanks @davidguttman.
+- CLI/logging: make pretty log timestamps always include an explicit timezone offset in default UTC and `--local-time` modes, so incident triage no longer mixes ambiguous clock displays. (#38904) Thanks @sahilsatralkar.
 - Feishu/startup: treat unresolved `SecretRef` app credentials as not configured during account resolution so CLI startup and read-only Feishu config surfaces stop crashing before runtime-backed secret resolution is available. (#53675) Thanks @hpt.
 - DeepSeek/pricing: replace the zero-cost DeepSeek catalog rates with the current DeepSeek V3.2 pricing so usage totals stop showing `$0.00` for DeepSeek sessions. (#54143) Thanks @arkyu2077.
 - Docker/setup: avoid the pre-start `openclaw-cli` shared-network namespace loop by routing setup-time onboard/config writes through `openclaw-gateway`, so fresh Docker installs stop failing before the gateway comes up. (#53385) Thanks @amsminn.
