It is an expression that takes the edge off of the overused phrase, "At the end of the day."

Utilize those last two minutes of your day to relax, and say goodnight to loved ones.
Two minutes before the end of the day the outcome of today's super important business meeting will be exactly what it was when the meeting ended, as well as exactly the same at the actual end of the day.
