the essential phrase in that source is:

Viele Kantone machten denn auch 1894 von ihrer Kompetenz Gebrauch und 
führten die mitteleurop. Zeit eigenständig nach z.T. heftigen öffentl. 
Debatten in ihrem Hoheitsgebiet ein. Seit 1894 richtet sich die Schweiz 
nach einem einheitl. Zeitsystem.

Many cantons (there are 23) made use of their competence in 1894 [[when 
the federal goverment introduced Central European Time for post, 
telegraph and railway which were under federal authority]] and 
introduced Central European Time by their own decision, after partly 
intense public debates, for their respective area of sovereignty.
Since 1894 Switzerland follows a uniform time system.

For TZ, this is not relevant, it only wants to know when the city of 
Zurich went to CET, as the zone Europe/Zurich does not claim to 
represent all of Switzerland for the period before 1970.

So, we may have different acceptance dates for different cantons, but 
the source above claims that they were all within the year 1894.
