This script populates optimal time zones for the United States based on an ideal solar noon window of noon—1pm. See http://outoftime.github.io/time-zones for a full description of the approach.
Install the dependencies:
$ pip install -r requirements.txt
You’ll need to download the data sets. You can get the county population data set here, and the county shapefiles here. Unzip the shapefile archive, and put everything in a folder called data/.
Now run it like this:
$ python time_zones.py data/c_13se22/c_13se22 data/co-est2021-alldata.csv
