If you don't have it installed, get rdate

then rename your mythfrontend binary (say mythfrontend.next) and create 
this script as mythfrontend

#!/bin/bash
rdate -p -s utcnist.colorado.edu
mythfrontend.next

Substitute another ntp source as desired.
Then you only need run a time check program on the server. (Note that 
this is not guaranteed to give the FE *exactly* the same time as the BE 
unless they use the same time-source...And I have NO idea how close the 
BE and FE have to be synchronized in order to not trigger an 
error...buried in the code somewhere???)

The other choice is to change the foregoing script to something like:

service ntpdate start
sleep 10
service ntpdate stop
mythfrontend.next

This depends upon how long your particular setup takes for ntpdate to 
actually update the time on the FE. AND you do need to have ntpdate 
installed on the FE. AND startup is delayed by the 'sleep' interval.
