So the people quietly acquiesced, reset their watches a few minutes faster or slower, and for the most part soon forgot that any but "standard time" had ever been in use.
In the present generation we have become so accustomed to the use of accurate time and the ready means of obtaining it, that we hardly realize how dependent we are upon it.
