+# Goal
+
+Make remote log timestamps ending in Z represent UTC.
+
+# State
+
+Set only the syslog formatter's converter to time.gmtime. This PR is independently based on integrated master. Local formatting, remote transport and application settings remain unchanged.
+
+# Decisions and why
+
+logging.Formatter defaults to local time. Its existing converter setting provides UTC without changing any global formatter behavior or requiring another open PR.
+
+# Surprises
+
+No inspected application manifest enabled remote logging. This correction does not establish server receipt.
+
+# Next step
+
+Read the corrected PR's existing package checks. No merge or release.
