AFAICT the internal conversion helper toUnixTimestamp has always been able to convert Dates - https://github.com/nodejs/node/commit/1d5ff15
Currently precision is platform dependant, but that could be fixed.

@nodejs/platform-aix - Should the AIX >= 7.1 note be added to utimes as well? #14154 (comment)

- Values can be either numbers representing Unix epoch time, `Date`s, or a
numeric string like `'123456789.0'`.
- If the value can not be converted to a number, or is `NaN`, `Infinity` or
`-Infinity`, a `Error` will be thrown.

Still "an Error"?

What happens if Invalid Date is passed?

Also, if we can pass a string that gets coerced to numbers, then I'm not sure we should put string in the docs.

  1. Still an Error in master - https://github.com/nodejs/node/blob/master/lib/fs.js#L1196
  2. Even a Date is converted (or coerced) to number so the sentence still stands true (Number(new Date("foo")) === NaN), just missing an explicit mention.

@benjamingr the string note was alway there. As for the arg type I think it's better to explicitly state string but this is JS1.0 semantics so we need to ask ourselves WWDCD?

Ack. But I'm not pushing a fix yet, so the string conversation will stay open.

Should the AIX >= 7.1 note be added to utimes as well?

No:

bash-4.3$ uname -a
AIX 1 6 00F460A94C00
bash-4.3$ touch g.txt
bash-4.3$ cat utimes.js 
var fs = require('fs')
fs.utimes(process.argv[2], 1, 2, () => {
  const stat = fs.statSync(process.argv[2])
  console.log(`file modified at ${stat.mtime} and accessed at ${stat.atime}`)
})
bash-4.3$ ./node utimes.js g.txt

No:

That's surprising since intuitively I'd assume utimes(path) := futimes(open(path)), but if no one complains 🤷‍♂️

basically fs.utimes is implemented by uv__fs_utimes and fs.futimes by uv__fs_futime and underneath mapping to system calls of the same name in most of the unixens, but platform specificity applies. AIX cases are here and here.

@refack as far as I see it there is little to do to get this ready to land, right?

I would otherwise close the PR sometime soon.
