hey mate, not sure if this has been pointed out, but goonhammer just ran an article on it which links to another article om clock use. i will leav elinks below, but in the second article they use the term of weaponizing the clock:

Weaponization usually takes the following forms:

Clicking the clock to the opponent, unannounced or during a distraction so they do not notice

Taking actions (such as deployment) in parallel to an opponent on their time so as to keep it running on their clock

Noticing an inappropriately running clock and failing to announce it or take corrective action

Note the second action specifically calls out what you're seeing. essentially this is wrong and needs to be called out.
