> Most likely utcCal.getTimeInMillis % MILLIS_PER_DAY == 0 but need to check that for all available time zones in the range of [0001, 2100] years with the step of 1 hour or maybe smaller. If this hypothesis is confirmed, floorDiv can be replaced by /, and this should improve performance of RebaseDateTime.localRebaseGregorianToJulianDays.
