UTC-conversion to local time or sun time
Currently the results of are returned in local time, however this becomes an issue when spatially aggregating over timeseries to get a global map, since timezones might break up areas into discontinous patches. Maybe Solar time should be used since the spatial shift in time is continous then. Thus results become less prone to computational outliers/errors due to the "jump" between timezones (espacially the international date border)
