FYI, see below for some information regarding the City of Fort Pierre SD USA time zone. It looks like Fort Pierre and the surrounding Stanley County unofficially use Central Time..

Most of Stanley County and Fort Pierre uses the Central time zone due to doing most of their business in Pierre so it simplifies schedules. I have lived in Stanley County all my life and it has been that way since I can remember. (43 years!) I hope this helps you. If you have any further questions let me know. Thanks!

I'm updating some geographic data, and I have a question about your time zone. I understand that Fort Pierre is officially on Mountain time, while Pierre is on Central time. However, based on your location right across the river, it looks like you might actually use the same time as Pierre. Could you tell me which time zone you use? If you do follow Central time like Pierre, do you know if the rest of Stanley County does likewise? Do you know if there is any history to the issue? If you do go by the unofficial Central time I will pass the info along to www.iana.org , a non-profit which (among other things) publishes a global time zone database used widely for computer apps and the like. Thanks for your help. Rick McDermid, Chilliwack BC Canada rickmcdermid@shaw.ca
