this is "one day" since Jesse is out of Moritat project and back to reality.
yes,It refers to the present day.
This is why Jesse has pierce marks in his neck, he got this after being connected to Moritat's project .If you remember when Jesse comeback to reality (on chapter 32) Jesse disconnected this from his neck in a violent way.

There was no way he could have these marks before of being connected to Moritat.
Another proof this is the present day is the last page of chapter 50. Jesse said Law is a "talker" or how he only let him some inofensive pierced marks after all.
I need to know what happened in all these years that they were separated and what Law did? because this seems he really did some shity things (to Jesse) in response to him forbidding Law to enter in the Brown mansion.
that's why Jesse is even studying in that place that he does not like and his reputation(from being from Brown Family) is not good thanks to Law.
Maybe Law allied with his mother or something since Jesse's mom is more powerful.(?)
ayyy Law,you and your fucking obsession to control Jesse >.< ..dude, Jesse just wanted to protect you from his mom and avoid that you keep becoming a total monster ¬¬ you idiot xD
