A helper to control the flow of time

Carbon is an excellent library to work with time in PHP projects. The Spatie\TestTime\TestTime class contains a few functions that under the hood manipulate the time that's considered the current time by Carbon.

// the flow of time is frozen
TestTime::freeze();

// we're now one year in the future
TestTime::addYear();

// will report the real current year + 1
$year = (new Carbon())->format('Y');
