Is there a concise way to strip out all the minutes, seconds, and nanoseconds in OffsetDateTime? Here is what I have to do to get what I want.
final OffsetDateTime strippedTime = OffsetDateTime.now().withMinute(0).withSecond(0).withNano(0);
System.out.println(strippedTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.nnnnnnnnn")));
The code above gives me:
2016-11-08 09:00:00.000000000
LocalTime.MIDNIGHT sadly strips the hours away from the object, so it is no use to me. Any suggestions appreciated.

It obtains an instance of OffsetDateTime from a text string such as 2007-12-03T10:15:30. It gets the range of valid values for the specified field. It converts this date-time to the number of seconds from the epoch of 1970-01-01T00:00:00Z. It returns a copy of this OffsetDateTime with the time truncated.
OffsetDateTime is an immutable representation of a date-time with an offset. This class stores all date and time fields, to a precision of nanoseconds, as well as the offset from UTC/Greenwich. For example, the value "2nd October 2007 at 13:45.30. 123456789 +02:00" can be stored in an OffsetDateTime .
You can use OffsetDateTime.truncatedTo(TemporalUnit) with ChronoUnit.HOURS:
OffsetDateTime.now().truncatedTo(ChronoUnit.HOURS)
