In that context "ET" stands for "European Time", and "EST" stands for
"European Summer Time".  This is explained in the "europe" file.

It does seem a bit odd that time in northern Africa is called
"European time", but that's what the first contributors submitted many
years ago, and we haven't had anyone tell us otherwise since then.
