Many people are not aware that Spain and Portugal, although sharing a common border, are situated in different time zones.
Portugal is on the same time as the UK and in winter is on GMT and in summer on GMT +1.00
Spain follows CET (Central European Time) and clocks are year round one hour ahead of those in Portugal.
Consequently, air, rail and train timetables for routes between the two countries reflect this.
This should be taken into account when planning trips between the two countries.
