The US voltage seems to always be headed up.  Years ago it was called 110.
I have some computer supplies from the 1990's and they have on them 115
volts.  Later items in the house shows 120 on the name tag.  

I have a digital volt meter that stays plugged in all the time and most of
the time it shows 122 or 123 volts.  Sometimes in the summer with a heavy
load on the power grid it will drop to 120 or maybe slightly lower. It may
go to 124 but I don't recall it hitting 125 yet.  I am sure it is accurate
as I have checked it with 2 Fluke meters that show the same thing at those
voltage levels.  Those meters were verified by comparing them with another
lab meter that was sent off and calibrated by a company that calibrates and
verifies instruments.
