I need to add x days to an instant. However, when I was using java.util.Calendar, I was adding the days in hours to avoid DST/ST crossover issues. Is instant + x.days equivalent to calendar.set(Calendar.HOUR, 24 * x)?

x.days yields a duration and not a calendar period. The duration of days defined by days is 24 hours and will be inaccurate during DST.

You should use a DateTimePeriod for your purposes.

myInstant.plus(period = DateTimePeriod(days = 5), timeZone = myTimeZone)
