We also save a script and it sits on all of our builds, Unfortunately, we are either busy or lazy :-) and we have the deployments change the script and run as need be, and we haven't done a UI. It extracts info from the wiki and summarizes some of what's here, but this process adds the local time-zone too, in this example EST. We cannot guarantee internet connectivity, hence this less elegant method. ==================================== Once Linux has booted, login at a root terminal (e.g. press Ctrl+Alt+F2) or perform as superuser: date --utc --set="2012-08-26 18:30:40" cd /etc ln -sf /usr/share/zoneinfo/EST localtime /sbin/hwclock --systohc shutdown (Don't force a shutdown by holding down the power button, because then the change won't be stored.) ======================================= Building an input UI for date and time-zone parms is on our list, just never seems to bubble to the top.
