I'm not sure why messages get out of sequence. I think it's the mail queue process -- if for some reason message 1 is delayed (ie, your mailhost is temporarily unreachable) it may be deferred for X minutes before trying again. If another message comes along after the temporary problem clears, it may go directly while the earlier message is still being held. That's a theory, anyway -- I haven't dug into it as the delays haven't been a problem (and they're not unique here -- I very frequently see this from the NTP mailing list server, which uses the same Mailman listserve software as I do). Re the Rolex -- I feel compelled to let the list know that all the servers at febo.com run ntp, and look to my (at the moment) two stratum 1 servers -- one gets its time from a Z3801A GPSDO, while the other uses both a Z3801A and a Spectracom WWVB receiver. I just checked, and the mailserver machine is currently offset about 0.3ms from those two sources. (When I get back from vacation, my first project is reconfiguring the NTP setup. I just acquired a stack of cheap 1U servers, and three of them -- named tick, tock, and toe -- will be running FreeBSD, each with one reference clock initially. After some software tweaking, I hope to be able to add the 1pps from my two Cesiums to the mix, so I'll have five reference clocks driving the time suite.)
