Hate to reply to my own mails, but ... I narrowed this down to something that does appear to be broken in -STABLE. If I remove *both* all CLK* options and the HZ= option, then the system maintains good time. If I add any of these options, then UNIX time is borked, even though the hardware clock continues to keep accurate time. Think this deserves a PR? Since I use this as both a band-width limiting firewall, as well as running an IDS that uses time-based statistical anomaly detection, I'd really like to reach a resolution because I really need HZ at less than the 100 default.
