OPTION 1: Had same issue and solved it in backed (Java) Can you solve this in your backend code.
Presenting java code in case if anyone needs the same help. concept should be similar for other server side technologies too.

Simulated the same bug and following are the analysis.

PRINT Via JSON | "startdate": "2018-02-08T18:30:00.000Z" .

PRINT BEFORE SUBMIT >>Fri Feb 09 2018 00:00:00 GMT+0530 (IST)

public static String dateConversion(String dt) {

        Instant timestamp = Instant.parse(dt);
        ZonedDateTime isttime = timestamp.atZone(ZoneId.of("Asia/Kolkata"));
        System.out.println(isttime);

        System.out.println(DateTimeFormatter.ofPattern("dd-MM-yyyy").format(isttime));
        return DateTimeFormatter.ofPattern("dd-MM-yyyy").format(isttime);
    }

OPTION 2: (solution in frontend) I have not tried this option but the documentation seems very clear.
