That is the setting I was talking about (I wonder why I said
"setting*s*" before, sorry for that).

It is used to address the problem that Windows expects the hardware
clock to have the local time value (hence "local"), that is, what you
see when you ask the computer what time is it. Because the usual setting
is UTC, that is, time with no timezone and/or DST "shift" - GNU/linux
does the math and shows you your local time. Local time clock forces you
(or the OS) to change it every time there is some DST change.

In other words, that makes linux use the hardware clock the same way
windows uses it.
