Oh, and to be clear, I’m not talking about efficiency. I’m saying that it does not support all versions of the ISO format. You have to do some ugly hacks and preprocessing.
Yes it requires some ugly preprocessing but it does support popular ISO 8601 date and time formats:
yyyy-MM-dd'T'HH:mm:ssXXX -> 2019-03-30T14:22:15+05:00
//set the timezone to UTC
yyyy-MM-dd'T'HH:mm:ss'Z' -> 2019-03-30T09:22:15Z
yyyyMMdd'T'HHmmss'Z' -> 20190330T092215Z
I updated the tutorial to include these ISO conversions.
Yeah, I know but there is no single formatter that supports parsing all ISO compliant timestamps. The biggest issue is the time zone options. There „Z“ as well as „+00:00“ and others as well.
Yeah, timezone options are a bit confusing for developers. Before Java 8, I even used to have a special DateUtils class for handling these ugly conversions at one place.
