The detection of timezone is performed by [ZoneDetect](https://github.com/BertoldVdb/ZoneDetect) timezone16.bin has a longitude resolution of 0.0055 degrees (~0.5km). timezone21.bin has a longitude resolution of 0.00017 degrees (~20m). The safe zone result indicates how close you are to the nearest border (flat earth model using lat and lon as x and y), so you can know when to do a new lookup. If you don't need it you can ignore it, in this case you can pass a NULL parameter to save the (very small) calculation effort. Note that the [underlying database](https://github.com/evansiroky/timezone-boundary-builder) will change from time-to-time.
