Getting milliseconds on a time stamp

BulldogLowell:
OP isn't asking for something that crazy/unreasonable.

Javascript's Date.now() returns number of milliseconds since 1970...

Does Javascript return Date.now() with milliseconds on a Yun?

Also, I don't really know how the clocks work but I am not really asking for millisecond since 1970, I am asking for the time to not be rounded to the second. I am asking for a partial second value be returned. This is very standard on Linux.

Here it is from a webserver:

~ >> date
Wed Oct 11 18:01:35 CDT 2017
~ >> date +%s
1507762903
~ >> date +%s.%N
1507762910.309654000

In fact, every Linux I have ever SSL'd into gives the same resolution.

I just can't get the partial second from the Yun.
