I've had a good amount of time to answer this but I didn't know the 12:01 connection. An enjoyable timed grid.

Awesome

Very fine work

Nice variation. Didn't quite get there.

Fell short at the second hurdle, nice one.

Couldn’t crack it ( only one group!) but I liked it!

Loved this, keeps you guessing to the end

I was almost there but I was timed out on the 5:20 connection and did not get perfection.

it could also be said of the 8.40 group that they are times that the hands meet, unless I worked that out wrong? The shipping forecast group was just evil, no way I'd get that but I was proud to (nearly) get two groups (the above and the palindromes), even if marked wrong! Great stuff

Intriguing and challenging, well done
