I have used behat many times in the past and today I've just got behat and selenium running headless chrome to make BDD acceptance features for custom development in Magento 2. Previous methods have either been custom to the framework I'm using or have used Carbon and code looks like...
//Carbon
Carbon::setTestNow(Carbon::create(2001, 5, 21, 12));
//Silverstripe Framework
SS_Datetime::set_mock_now('2003-11-01 12:12:12')

I am now looking for the same thing within Magento CE 2.2.7 and have so far not found what I'm looking for. There is a dev doc page that hints at this stating...

Can anyone please help me with this?
