I disagree. The datetime 2022-02-22 02:02 specifies a point in time, not
a time period. It means 2022-02-22 02:02:00.000000000.....
In reality, a point in time may be fuzzy. "The train departs at 02:02"
definitely doesn't mean that the train will depart exactly at 02:02:00,
but it also doesn't mean that it will depart between 02:02 and 02:03.
Rather it's a smooth probability distribution starting a bit before
02:02:00 (a train should never leave early, but sometimes clocks are
wrong or somebody doesn't pay attention) a peak shortly after 02:02:00
and a very long tail.

Depends on the context, but without s specific context (like business
days) I would agree. A day *is* a time period with a beginning and an
end.
