You have read the page @OvermindDL1 linked you to? It tells you to use Timex.format.

also on another note, I can just deduct that microsecond that I added and then the date value is the same, and it keeps the format

If you want to format a time for presentation use Timex.format, the inspection output is for debugging only and might change its presentation without any warnings.

Hmm, as per the documentation I linked I don’t see why this wouldn’t work for you based on the information given?
iex(1)> Timex.format(DateTime.from_unix!(1549385336000000, :microsecond), "%FT%T.%f%z", :strftime)
{:ok, "2019-02-05T16:48:56.000000+0000"}
iex(2)> Timex.format(DateTime.from_unix!(1549385336000001, :microsecond), "%FT%T.%f%z", :strftime)
{:ok, "2019-02-05T16:48:56.000001+0000"}

actually it gives back an incorrect value,
{:ok, "1970-01-01T00:25:20.672400+0000"}
only the microsecond changes, so I have a normal DateTime at the start and as I saw you use from_unix so I changed the date with the DateTime.to_unix() and then gave it to this function but it only gives 1970-01-01 as a result no matter the date I give to it

How is that an incorrect value? It works down to microseconds in formatting, although your DateTime you gave it didn’t seem to have that (not a formatting problem) so it was zero’s.
That’s still changing the displayed time from what it actually is. Rather are you absolutely sure beyond any doubt that your DateTime that you are passing in actually has microsecond time? I’m not sure that changing the displayed time from the stored time is really a good “Solution” post as it could easily break things that other people may try to do the same with if all they read is that post and nothing else. ^.^;

oh nono, maybe I miss typed or something, but the issue was this: my saved times doesn’t have microseconds, but the app expects them for parsing reasons, not for any other use, so I just needed that DateTime to have microseconds in the format.

Then please use proper formatting instead of relying on debug output that may change without a warning at any point in time.

Oh! Then my snippet should work perfectly for it as it always prints microseconds, even out to full 0’s if the datetime doesn’t contain them. You really don’t want to change a time to print out for something else, you’d be surprised by the bugs that can happen. ^.^
