About time in Portsmouth

Portsmouth keeps British Summer Time, UTC+1 from UTC at the moment. Clocks move twice a year, so the same wall-clock time is a different instant in summer and winter — this page reads the offset in force today rather than an average.

Portsmouth shares the zone Europe/London with London, Birmingham, Liverpool, Nottingham, so a time here is also the time there. One canonical page per zone keeps the difference honest: the settlement name changes, the clock does not.

Offsets and daylight saving rules come from the IANA time zone database — see IANA time zone notes for what that data does and does not promise about future dates.
