Hi All,

        I'm facing some strange behavior with an skew in the system clock.
The hardware is a Dell PowerEdge 2950III, running two instances of FreeBSD 7.0-RELEASE-p5 - amd64 over an ESXi hipervisor. To both were allocated 4 processors and 4 GB of RAM, and dmesg for both are identical. I'm using clockspeed to synchronize the clock, but just one of them is delaying the clock a lot.
        The hardware clock is ok as far as the other virtual machine.
        Where should I start to investigate?
