David, It depends on the value of the longitude. France is rather wide.
If e.g. the longitude is east and smaller then 7.5 degrees E you are right. If the longitude is larger then 7.5 degrees E then you are wrong. At 15 degrees E the hourline for 12 is in winter in top. See the attached example for Paris with latitude 49 N and longitude 2.3 E for wintertime. Best wishes, Fer.

I must be getting old................... I'm doing a design for an analemmatic dial in France. France is in the GMT time zone but chooses to be +1 on GMT in the winter months and +2 in the summer months (daylight saving). I have the co-ordinates etc for the dial's lat and long - no problem here. Am I right in labelling the hour points as follows, for showing winter months............... The hour point nearest to the meridian line (which would have been 12 in UK) will be 1 pm in France. If the dial is to indicate daylight saving hours, then the point nearest top the meridian will be labelled 2pm.
