True. But depending on where on earth you are located and what time zone that location follows, DST is closer to the real Solar Time (12 o’clock is Solar noon). Like Poland follows CEST but in the eastern part of the country the Solar time is close to an hour ahead. So DST is more in sync to the actual natural time.
CE(S)T reaches all the way to Finisterre in (Spanish) Galicia, well past Greenwich, which should be one hour behind, so basically at least 3 times zones. I blame Hitler.
Which is why I specify tz database timezones, like “America/New York”. Pick the one that’s the city closest to you and will be on the same daylight savings time switchover dates. Then don’t worry about specifying EST or EDT or whatever.
I just use UTC for anything technical. Specific timezones should only be used by clients, and every client I know about can convert from UTC to their local timezone. Honestly, I wish we’d do this as a matter of public policy, everything is denominated in UTC, and you can use whatever local conversion you choose to display the time.
DST is only marginally useful for things like schools and offices, and even then it has pretty limited utility.

Franco, actually.
Both to be pedantic. Hitler put France on it, Franco decided that the fascist world should share a time zone.
Universal Fascist Time. Don’t tell Trump.
