Hi,

I'm wondering why DateTime.toSeconds() does return a floating-point number xxxxx.yyy where yyy represents the milliseconds. If I wanted to have milliseconds I would have called .toMilliSeconds()

Expected:
DateTime.fromISO("2019-08-31T00:27:39.689Z").toSeconds() // --> 1567211259

Actual:
DateTime.fromISO("2019-08-31T00:27:39.689Z").toSeconds() // --> 1567211259.689
