How to create UTC date without extra UTC string

[Alex Mills]

I have this date string:

"2020-09-23 18:31:41.015852841 +0000 UTC"

the above is generated via:

time.Now().UTC().String()

my question is, how can I generate a date string like this:

"2020-09-23 18:31:41.0158"

and how can I then parse it?  I dont need to indicate that it's UTC, I can assume it's UTC.

But I want to include 4 decimal points.  1 digit more granular than milliseconds, whatever that's called (trivia!).

My guess, is that a starting place would be something like:

var s = time.Now().UTC().String()[0:24]

an example of which looks like:

"2020-09-23 18:41:43.1568"

so I guess I just to know if there is a reliable way to parse that string back into a date using multiple programming languages.

See https://golang.org/pkg/time/#Time.Format

Here's how to use it. I think this is exactly what you want:
