+Subject: [PATCH 11/16] sysklogd: add -Z option to adjust message timezones
+
+Some syslog() implementations like musl's[1] always send timestamps in UTC.
+This change adds a new option to syslogd, -Z, to assume incoming timestamps
+are always UTC and adjust them to the local timezone (of the syslogd) before
+logging.
