Something you may not know about DST
I stumbled across this and it made me feel…well…not educated!
The official spelling is Daylight Saving Time, not Daylight SavingS Time.
Saving is used here as a verbal adjective (a participle). It modifies time and tells us more about its nature; namely, that it is characterized by the activity of saving daylight. It is a saving daylight kind of time. Similar examples would be a mind expanding book or a man eating tiger. Saving is used in the same way as saving a ball game, rather than as a savings account.
Adding to the confusion is that the phrase Daylight Saving Time is inaccurate, since no daylight is actually saved. Daylight Shifting Time would be better, but it is not as politically desirable.
