It varies every day
30 Sep. 1972 London sunrise: 7:00 AM BST
Sunrise was at 7:29 AM GMT.
22 Dec 2009 London sunrise: 8:04 AM GMT
Sunrise has nothing to do with time zones. French official time is indeed an hour ahead of British, but sunrise in Paris depends on the sun, not the clock. London is on zero longitude, Paris on 2'20" East, so sunrise comes there earlier. How much earlier? Well, the earth spins 15 degrees per hour, so one degree makes a difference of 4 minutes, so Paris' sunrise is 9 minutes 33 seconds earlier than London's.
Sunrise in London on 30th May was at 04:50... Therefore the total time between sunrise and noon was 7 hours 10 minutes.
Odd question. Cities that are East of you, are earlier. The sun rises in the East so they see the sunrise before you do. Therefore London time is 8 hours(I believe) ahead of your Pacific time zone.
The time of the sunrise in Denver changes depending on the time of year. See the related link below for the time of tomorrow's sunrise in Denver.
The sunrise time on January 21, 2009, would depend on the specific location, as sunrise times vary by location. You can check the exact sunrise time for that date and location by using an online sunrise/sunset calculator or checking a local almanac.
Example: Paris (place A) is ahead of time than London (place B), because sunrise occurs earlier in Paris.
