I do not think so? MEZ (CET) was introduced in 1893-04-01,
Sure, but Berlin was under Russian control just after World War II and the Russian commander of the city decided to run Berlin's clocks on Moscow time because that matched the Red Army's clocks. This is why Europe/Berlin is known to be wrong for most of Germany, as well as for Norway and for Sweden. Really, nobody should be taking the pre-1970 part of tzdb seriously unless they really know what they're doing, which they probably don't. That part of tzdb is meant primarily to demonstrate that the infrastructure can in *theory* specify pre-1970 civil time, even though you generally don't want to be *using* that specification outside of artificial Zones like PST8PDT and Etc/UTC.
