GMT, Greenwich Mean Time is the standard time set for UK. It is the time kept for that location in London, though because of pollution etc, the observatory may no longer be there. GMT does not vary with daylight savings.
For international use, the equivalent name is either UT (Universal Time) or UTC (Coordinated Universal Time). a.k.a. Zulu time or Z time for some applications.
[Actually, the time of the Sun's transit at Greenwich varies by up to 16 minutes throughout the year, due to imperfections in the Earth's spin, and of its orbit around the Sun. Known to those who need to know as 'The Equation of Time'.]
