'Daylight Savings' Is Grammatically Incorrect (qz.com)
A reader shares a report: We talk about time like it's money, and that may explain why we say "Daylight Savings Time," capitalizing the concept to emphasize its awesomeness. After all, who wouldn't want to be able to save hours like cash? The phrase "Daylight Savings Time," though commonly used in Australia, Canada, and the US, is technically incorrect. Time and Date, a website devoted to all things chronological, posits that the plural "savings" became popular because it's used in everyday contexts, like "savings account." The grammatically correct usage is "daylight saving time." The expression is singular and not capitalized, according to the US Government Publishing Office style guide. The GPO provides the guidance, "d.s.t., daylight saving (no 's') time."
We now have a grammar nazi post on the front page. Slashdot has really evolved, from the nascent grammar troll posts, through the mercurial grammar nazi years, to a full fledged front page grammar post.
I'm going to continue to say Daylight Savings Time, because that is how nearly everyone says it, and alter the language irrevocably. In 50 years, hopefully we will have done away with daylight savings time completely and this topic will be dead, but if we have not, Daylight Savings Time will be the correct way to say it.
