To be clear: the measured TSC frequency of 745 MHz seems too low. There is something probably relevant that I noticed while setting up a new VM guest to try to compile the kernel as advised. So, ISO used was a current snapshot (sha256: 29d320ae1a...), and as always in "VM Options" under "General Options", "Guest OS Version" was set to "FreeBSD (32-bit)". Issue with clock running forward is again reproduced. Being curious what would happen if that same option was set to "FreeBSD (64-bit)" I tried it and the clock issue is gone! (but ESXi now shows a warning in web GUI: 'The configured guest OS (FreeBSD (64-bit)) for this virtual machine does not match the guest that is currently running (FreeBSD (32-bit)). ...') Attached are dmesg, sysctl hw and sysctl machdep outputs from this new VM running with both 32 and 64 bit settings. *Nothing* else was changed, virtual machine was untouched after installation. Notable difference is machdep.tscfreq=3392313140 (64-bit) vs 744231460 for 32-bit setting. Hope this helps for now. Just noticed hw.sensors.vmt0.timedelta0 and hw.cpuspeed are also different depending on Guest OS Version option! For 32-bit option (reproducible clock issue): hw.sensors.vmt0.timedelta0=738.817611 secs hw.cpuspeed=744 For 64-bit option (no clock issue): hw.sensors.vmt0.timedelta0=941.876986 secs hw.cpuspeed=3392

Unlikely to be related to the time issues. These can happen if the machine is restarted without bringing down the connection nicely first and the ISP holds onto the old session for a while. "ifconfig pppoe0 down" in rc.shutdown, possibly followed by a short sleep, might help with those.
