What time zone will I be in???

Greetings from sunny London..yes, you heard me right..sunny! High of 73 today and 77 tomorrow. That's basically unheard of or so I am told. Anyhow, I proclaim that I am no longer Eeyore. Everyone has said that I brought the beautiful weather and that's the story I'm sticking to. Perfect day for a boat ride, so I am heading to Greenwich where you can stand on the GMT line (google it if you don't know what GMT is). The pics should be fun! Is it 12, 11, 1pm? Stories from the day to follow.
