BloombergLP::baltzo::TimeZoneUtil::addInterval

Load, into the specified result, the local time value that is the specified interval in the future of the specified originalTime (in the time zone originalTime.timeZoneId()). Return 0 on success, and a non‐zero value with no effect otherwise. A return value of ErrorCode::k_UNSUPPORTED_ID indicates that targetTimeZoneId was not recognized, and a return value of ErrorCode::k_OUT_OF_RANGE indicates that the result of the operation would have been outside the range of values representable by the result type. The resulting local‐time is equivalent to adding interval to originalTime.datetimeTz().utcDatetime() and converting the result into the local time of originalTime.timeZoneId().
