Given a `Path`

, I would like to determine the file's age based on last modified time. I know how to get the last modified time:

```
FileTime t = Files.getLastModifiedTime(path);
```

I also know how to get the current date/time with:

```
LocalDate now = LocalDate.now();
```

However, I failed to see any connection between the two. I imagine I have to convert from one type to anther, then calculate the diff in days, but I am stuck at reading the documentation at this point. Any help would be greatly appreciated.

I wouldn't use `LocalDate.now()`

- that depends on your current time zone. A file's age in days of *elapsed* time can be computed in a time zone neutral manner.

Instead, convert the `FileTime`

to an `Instant`

via `toInstant`

, and then you can find the duration:

```
Instant fileInstant = t.toInstant();
Instant now = clock.instant(); // Where clock is a java.time.Clock, for testability
Duration difference = Duration.between(fileInstant, now);
long days = difference.toDays();
```
