db.foo.aggregate({$project:{milli:{$millisecond:"$date"}}})
{ "_id" : ObjectId("5984bd888a8d0117a3bbb81d"), "milli" : 0 }
{ "_id" : ObjectId("5984bd888a8d0117a3bbb81e"), "milli" : 374 }
but
db.foo.aggregate({$project:{date:{$dateFromParts:{millisecond:318,year:1970}}}})
assert: command failed: {
"ok" : 0,
"errmsg" : "Unrecognized argument to $dateFromParts: millisecond",
"code" : 40518,
"codeName" : "Location40518"
} : aggregate failed
// but
db.foo.aggregate({$project:{date:{$dateFromParts:{milliseconds:318,year:1970}}}})
{ "_id" : ObjectId("5984bd888a8d0117a3bbb81b"), "date" : ISODate("1970-01-01T00:00:00.318Z") }
And $dateToParts returns: "year" : 1975, "month" : 6, "day" : 12, "hour" : 0, "minute" : 0, "second" : 0, "millisecond" : 0
So I think this milliseconds is a typo.
