At each change of scene, the locale and time are posted across the bottom of the screen in high tech-looking green letters, with the time given in the military-style 24-hour format, with the "Zulu" designation to define locale. The trouble is, "Zulu" means Greenwich Mean Time, and the time designated for the scenes is always the local time, which the military designates as "Lima". Do the show's producers really wants us to always know what time it is in London? If so, they are usually wrong, unless the action in the scene happens to be taking place in that time zone!
