Timex.Timezone.convert/2 question

Can you give a more complete example about how you create the dates and how you convert them?

sure, I have the dates saved in the db, and before returning them to the fronted, I run them through the function in the title

def parse_datetime_with_timezone(datetime, timezone), do: Timezone.convert(datetime, timezone)

The dates in the db do not have milliseconds, but it has been like that forever, and as I said before it returned them with the milliseconds.

or how could I add back the milliseconds?

I fixed it liek this:

Timex.add(datetime, Duration.from_microseconds(1))

That would change the time, making comparisons fail and so forth.

Since Timex doesn’t store time in the format shown in the first post, I’m guessing that a display function is being used that elides the trailing zero’s. If you could show that call that you use to print it then can show you how to adjust the formatter to keep the trailing zeros.

Hey, thank you, I’d appreciate that!

So if you can see my second command I had that function to add the time zone to the date, and that function is being called by the view with the date that is contained by the corresponding item.

So what I would need is that the convert returns the date with the trailing zeros.

I used IO.inspect to print the dates out of you meant that

Oh that is why! Timex prints out a shortened representation of the time it represents for debugging purposes. In general inspect is only for debugging purposes, not for an user interactions, instead you will want to use the formatting functions and guide available at:

I wrap up my calls in functions to call, as my workplace likes a very…non-standard way of displaying dates for compatibility with older systems. ^.^;

Hey thanks, but how will one of these give me the format I want?

The format specifiers are described here:

I think {ss} is the one you need for displaying the milliseconds.

Thanks, but how do I actually use that?
Because this:
DateTime.Formatter.format(datetime, {ss})
obviously says that “ss” does not exist
or this one:

Timex.Format.DateTime.Formatters.Default.format()

with this one:

Timex.Format.DateTime.Formatters.Default.format(datetime, "{ss}")

it gives back this: {:ok, ""}
