Depending on the time zone back in the States, there should be little to no adjustment.
Just DON'T CHANGE YOUR WATCH WHEN YOU GO HOME!!
Stay on Argentina time!!
For instance, right now TEXAS (except El Paso) is BA -3.
Dallas/Austin/Houston 7:30pm = 10:30pm Buenos Aires
It's easy to just keep the same schedule.
D/A/H bars close at 2:00am = 5:00am Buenos Aires (a little early, but not terrible)
D/A/H people wake up at 6:30am-7am = 9:30am-10am Buenos Aires time (a little early, but not terrible
)
Problem solved.
