How to set DateTimeFormatter.Local? about logparser

[nielsbasjes]

Try changing your logformat to replace the %t with the appropriate %{format}t value.
Here you can find the supported fields: https://github.com/nielsbasjes/logparser/blob/master/httpdlog/httpdlog-parser/src/main/java/nl/basjes/parse/httpdlog/dissectors/StrfTimeStampDissector.java#L200

Looking at your example I would guess something like this: %{%d/%b/%Y:%H:%M:%S %z}t

To verify I added an extra test in the code base with this timestamp.
This works as I expect it to work:

    @Test
    public void testReportedSpecialTime() throws Exception {
        String logline = "28/feb/2017:03:39:40 +0800";
        String logformat = "%{%d/%b/%Y:%H:%M:%S %z}t";

        DissectorTester.create()
            .withDissector(new HttpdLogFormatDissector(logformat))
            .withInput(logline)
            .expect("TIME.EPOCH:request.receive.time.epoch", "1488224380000")
            .checkExpectations();
    }

I verified the result using this
