Building a custom date format to include milliseconds: 2020-06-11T03:18:30.000Z

[#1]

I have used the custom date format generator to produce this custom format (which does not work):

<YYYY><-><MM><-><DD><'T'><hh24><:><mm><:><ss><:><ss>

The format I received from Twitter has th period between seconds and hundredths, but that is not an option in the date format builder.

The issue might be with the Z, not with milliseconds.

Names Default To Here(1);

date_str = "2020-06-11T03:18:30.123Z";
Show(Informat(date_str, "Format Pattern", "<YYYY><-><MM><-><DD><'T'><hh24><:><mm><:><ss>"));
//drop Z
date_str = Left(date_str, Length(date_str) - 1);
Show(Informat(date_str, "Format Pattern", "<YYYY><-><MM><-><DD><'T'><hh24><:><mm><:><ss>"));
date_with_ms = Format(date_formatted, "yyyy-mm-ddThh:mm:ss", 25,3);
show(date_with_ms);
