Summary

Console log timestamps (e.g. 01:01:39 [canvas], 01:00:31 [ws]) are always displayed in UTC, even when:

• System timezone is set to Asia/Tokyo (JST, UTC+9)
• env.TZ: "Asia/Tokyo" is configured in openclaw.json
• logging.consoleStyle: "pretty" is set

Root cause (from source)

In subsystem-DkqfG4LL.js, formatConsoleLine() uses:

if (opts.style === "pretty") return color.gray((new Date()).toISOString().slice(11, 19));

toISOString() always returns UTC. Slicing [11,19] extracts HH:MM:SS in UTC, ignoring the local timezone entirely. This applies to all pretty and compact styles.

Expected behavior

Log timestamps should reflect the local timezone (as configured via TZ env or system timezone).

Suggested fix

Replace toISOString().slice(11, 19) with local-time methods:

if (opts.style === "pretty") {
  const h = String(now.getHours()).padStart(2, "0");
  const m = String(now.getMinutes()).padStart(2, "0");
  const s = String(now.getSeconds()).padStart(2, "0");
  return color.gray(`${h}:${m}:${s}`);
}
