Forgive the stupid question, but why do we all put a "Z" after all
times?

I have always assumed that "Z" = "GMT" but what exactly does "Z"
mean?

Brendan


Z = zulu time = UTC

The globe is divided up into 15degree time zones, each having a unique
letter; the zone immediately to the east of us here in the BI is 'A' (or
Alfa), hence when UK is on GMT+1hr during BST, then reporting in local
time you would put 0824A etc. Z is reserved for the 'primary' zone
centred on the Greenwich meridian.
