Timezones are always computed by their difference to UTC, the "Universal Time Coordinated". In France exists only a single tonezone at UTC+1. E.g. New York has the Eastern Standard Time at UTC-5 and the time difference between NY and France is 6 hours.
They have a nationwide clock change from standard time to daylight saving time, where the clocks are switched forward by 1 hour in summer.
The next clock change in France will be on March 28th, 2021 at 2:00 to daylight saving time. Back to overview: France
