Parse Instant without second

Question

I have date in string "2015-05-08T02:56". As you can see it doesn't have seconds.

When I try to parse it with:

Instant instant = Instant.from(
        DateTimeFormatter.ofPattern("yyyy-MM-dd'T'hh:mm")
                .parse("2015-05-08T02:56"));

I get Exception

Exception in thread "main" java.time.DateTimeException: Unable to obtain Instant from TemporalAccessor: {MinuteOfHour=56, HourOfAmPm=2},ISO resolved to 2015-05-08 of type java.time.format.Parsed

How to parse this date correctly and fill seconds with 0?

Answer 1

I forgot to specify timezone

Instant instant = Instant.from(
        DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm")
                .withZone(ZoneId.of("UTC"))
                .parse("2015-05-08T22:57"));

works fine.

UPDATE: Also I had another problem I used hh instead of HH.
