"Roll on 11pm UK time on Friday, 29 March 2019."
Yup. And there's a nice little bit of irony that has gone over your head. The moment of our leaving is actually midnight.
EU time. Heheh.

How is 'EU time' defined? The EU (even excluding UK) does not operate within a single time zone. Of course, if you meant CET (Central European Time) you would be correct.
