I dont know how GPG is affected by a wrong clock, but your system is
affected for sure. Log reports shows the wrong time, you mail will
either be sent in the future or be old. Dont know how much your clock is
wrong but i've mail sent from the year 2005 etc. I suggested you
"invest" in a ntp daemon.

If you trust the machine secure copying is an option, but a more
convinient way is to get hold of a usb storage device (that should be
able to be in read-only mode) or burn it to a cd so you can transfer it
between the machines and umount it when you dont use it.
