/etc/localtime is symlinked to a file that contains time zone data. If you
enter the command

file -L /etc/localtime

you'll see that that's the case. It contains data that's not meant to be
displayed including control characters which cause the effect you observed.
If you cat any so-called binary file such as this you are likely to see the
same kind of thing happen. Entering the


command in the affected terminal will correct the problem after it occurs.
