According to issue #409
There is absolutely no reason for the timezone to be in UTC, and converting the local times to UTC while keeping values is hacky at least.
Excel has no understanding of timezones, hence the user of this library should know what timezone their values are supposed to be, by following the timezone within their timeTime structs.
