People going from the Netherlands, Denmark, or Austria to Germany, Italy or the Czech Republic need not think of time zones as they stay in the same. This time zone also includes Sweden and Norway, Hungary and Poland, Albania, Switzerland, Luxembourg, Belgium and Spain.
However, if you go from one of these cities further east to Rumania, , Greece and Finland, your watch is slow: Bucharest, Sofia, Athens, and Helsinki are one hour ahead.
If you turn you back to Germany and move west to the UK, or Portugal, your watch is fast. So, London, Reykjavik and Lisbon are an hour behind.
