Returns a copy of this {@code ZonedDateTime} with the specified number of hours added.
!(p)
This operates on the instant time-line, such that adding one hour will
always be a duration of one hour later.
This may cause the local date-time to change by an amount other than one hour.
Note that this is a different approach to that used by days, months and years,
thus adding one day is not the same as adding 24 hours.
!(p)
For example, consider a time-zone, such as 'Europe/Paris', where the
Autumn DST cutover means that the local times 02:00 to 02:59 occur twice
changing from offset +02:00 _in summer to +01:00 _in winter.

!(li)Adding one hour to 01:30+02:00 will result _in 02:30+02:00

!(li)Adding one hour to 02:30+02:00 will result _in 02:30+01:00
