Zulu Time (Z) = Greenwich Mean Time (GMT) and is constant, currently 1 hour behind British Summer Time (BST). Unfortunately over here times for events will often be given as GMT when they really mean BST as many people don't understand the difference, so using Zulu instead should remove any doubt - or at least make people ask "What time's that then?"

In Elite: Dangerous they are using GMT but calling it Galactic Mean Time. Hehe!
I am used to using GMT/Z being a Radio Amateur as we are required to log contacts using it. As I am typing this the time is 10:04 BST or 9:04 GMT. Smiley
Dang, Flossy! I did not know you were an Amateur! 73's! Although I never obtained a license, I did work extensively with Amateurs when I was in service and worked within the US Army MARS system running phone patches back in '69-'70. I salute you and all other Amateurs who made those phone patches possible!
I was NCOIC of two stations during that time frame:
AB9AB in Sattahip, Thailand
AB8AAT in Da Nang, Viet Nam
We ran Collins SSB transceivers and 30L1 linear amplifiers in Thailand, and 30S1 linear amplifiers in Viet Nam...pretty archaic by internet standards today but pretty good for the time!
Some of my best memories are of being able to connect GI's to their families and on a very good 12 hour shift to be able to run with an Amateur and log 30 patches or more whilst in a net. Some Veterans remember the horror of war by the friends they lost; I remember it by the number of patches I helped make possible with the help of folks like you.
