I'm pretty sure that its one of the newer ones because on OS Buddy it doesn't show any solutions.
Its just a regular text clue which says:
'He knows just how easy it is to lose track of time'
I've looked online everywhere and can usually find a solution so if anyone has done this one before or has any idea how to find this out for me then I would be very grateful :)
I would check reddit, I know they have a topic for new clue answers.
thanks man
