Yes, I think you'll find that offset is the difference between Greenwich
Mean Time and Paris Mean Time.

Before the international conferences that defined time all over the
world in terms of GMT and integer (mostly) offsets therefrom, France
would have been using Paris as their Prime Meridian - natural enough,
every nation assumes it's capital is the centre of the world, the hub of
the universe.

Although what a country that has a large extent in longitude (e.g. the
USA or USSR) would do in this case, I am unsure.
