In X there is "Sinza" that accelerates the whole sim. In X3 you had to attach a rubberband to the stick to fake input so it wouldn't deactivate. In X4 the devs removed that exploit barrier but I found myself barely using time acceleration at all. It was made as a means to shorten travel times but like in ED X devs shifted towards faster travel speeds and this came out at the sweet. And making money by running sinza all night isn't really that hot.
