Is daytime drinking really that bad?

lets say if you woke up at midnight and started your day there, by the time its mid day it would be your evening right? you have been up for 12 hours so if you had woken up at 8 am, then it would be 8 pm, 12 hour difference. so to you, its the evening and you would be getting into bed soon (if your sleep sched was bad cus you didnt have to work) so to you, its past 5pm where drinking is more likely but to everyone else, you are daydrinking, they probably dont know you have been up for a while and just think you day drink but to you, is it normal?
