Wikipedia excerpt:

In 1905, the prominent English builder and outdoorsman William Willett
was inspired to invent DST ...

I fail to see how he (Williett) can be said to have "invented" it since
Franklin published the idea in the 18th century predating his discovery
by some 120 years...

This article discounts anything other than the satire, but I think there
was more to it than that even though it wasn't widely adopted.

Standard time was invented by the railroads in the United States in the
1800s, long after Franklin was dead. It was even called "railroad
standard time." They did it so that trains could run on some semblance
of a schedule. Prior to that, and for some time thereafter, each
community had its own time, which varied widely. Confusion about whether
someone was referring to local or "railroad standard" time led to the
abandonment of local times and the adoption of railroad time as the
official standard.

Since DST is an adjustment to standard time, it's hard to say that what
Franklin proposed was DST.

I guess if you believe the history books, though, everything that exists
was invented by either Franklin or Edison.
