[tlug] Serious clock wrongness

["Michael(tm) Smith" <smith@example.com>]

I have a problem with the clock of a Linux VM that I'm running as
a guest OS under Parallels on a MacBook.

While the clock in OSX on the machine always displays the time
accurately, the clock on the Linux VM, aftter being set to the
accurate time at startup, runs slowly -- losing a secord or two
every few minutes.

Any suggestions for how I can troubleshoot what exactly the
problem is and/or some (automated) workaround I can use to correct
the clock (other than manually running hwclock or whatever at
periodic intervals)?
