timer doesn't work properly for large intervals

Bug Report

Current Behavior
If you start a timer with a time longer then 24 days, it emits all values immediattely. Using any time for up to 24 days (or even some fraction between 24 and 25 days, it breaks somewhere in the middle).

Reproduction

• REPL or Repo link: https://codesandbox.io/s/serene-franklin-cuj64 (I used a take(100) here just to limit the amount of output).

import { timer } from "rxjs";
import { tap, take } from "rxjs/operators";
import ms from "ms";

timer(0, ms("25 days")) // if you change this to 24, it works fine (supposedly, I didn't wait 24 days to see the next emittion, but it doesn't do it immediattely)
  .pipe(
    tap(e => {
      console.log("tap", e, new Date());
    }),
  )
  .subscribe();

Expected behavior
A clear and concise description of what you expected to happen (or code).

Environment

• Runtime: Chrome v78
• RxJS version: 6.5.3, also tried with 6.3.3, 6.0.0 and even 7.0.0-alpha.0
