What's Swift current time Date object precision when it is initiated using the default constructor?

What’s the current time Date object time precision when it is initiated using Date()? Does it capture the time to milliseconds?

let currentTime = Date()
print(currentTime) // 2022-10-09 09:13:39 +0000

When I print the date it only shows 2022-10-09 09:13:39 +0000 so I wonder if its precision is only to the second.

Yes, it does. printing a date shows a fixed string description omitting the fractional seconds. A hint is that TimeInterval is defined as a floating point type (Double).

You can prove it

let interval = Date().timeIntervalSince1970
print(interval)

which shows a real fractional part rather than a Is-floating-point-math-broken value like .00000003
