sorta. From France to Poland is one time zone. England/Ireland is an hour behind and Ukraine and Romania an hour ahead.
I knew England was an hour behind Europe but don't count them as Europe. Brexit! Plus they never adopted the Euro and kept their stupid pound currency. England, the new Switzerland.
Western France is kinda pushing it for the zone anyway. Weird to be pushing 9:30 p.m. and still daylight in Normandy in the summer when you're used to zones across the states balancing things out (mostly).
