If you're using a US English keyboard layout, it's the default and you won't have to deal with changing it.

Otherwise you may be sailing through life unburdened by what can be a major pain to anyone anywhere else in the world, like a resident of Arizona wondering why the rest of the world keeps messing with their clocks.
