Yeah.  Don't mess with the system clock.  Seriously.

There is pretty much no reason for anybody not to be running NTP these 
days.  Every OS ships with it, and there's gazillions of open NTP 
servers to use as references.

NTP will keep your system clock accurate to within a fraction of a 
second and avoid all the horrible problems such as the one you've 
discovered with pexpect when you reset your clock.
