…#2869) Two NIOFileSystem tests are still a bit flaky after (mostly) fixing them in #2842. ``` Test Case 'FileHandleTests.testSetLastAccessAndLastDataModificationTimesToNil' started at 2024-09-06 10:12:54.006 /__w/swift-nio/swift-nio/Tests/NIOFileSystemIntegrationTests/FileHandleTests.swift:1265: error: FileHandleTests.testSetLastAccessAndLastDataModificationTimesToNil : XCTAssertEqual failed: ("1725617573.0") is not equal to ("1725617574.006952") +/- ("1.0") - Test Case 'FileHandleTests.testSetLastAccessAndLastDataModificationTimesToNil' failed (0.001 seconds) ``` This is because we were dropping the nanoseconds when comparing the timestamps, which means that sometimes the two timestamps were off by just over a second. This change includes the nanoseconds to avoid this problem.

Two NIOFileSystem tests are flaky. This PR makes them less flaky.
Motivation:
We want fewer flaky tests.
Modifications:
Floatwith a cast toDoubleinstead. The number of seconds since the Epoch is over a billion, which is beyond the "accurate" precision for the non-decimal part of aFloat. The theory is that the numbers we're comparing are high enough that they start diverging wildly.Result:
Less flaky tests.
