Dataset to Standarize Time Across Time Zones

[ratgdillon]

Right now I have some data that involves date/time and city/state/country. All times are recorded in Eastern Standard time, but some entries are in different time zones. I would like to visualize this data by hour of day. I want to download a dataset that includes time zone by county or city so I can link it to my dataset to compare time of sales across geography.

Any suggestions?

City	State	County	Country	Sales	Date	Time
Dallas	TX	Dallas	US	$42.00	8/23/20	9:14:09 PM
Fiskdale	MA	Worcester	US	$12.00	8/15/20	12:39:16 PM
Centerville	CA	Fresno	US	$30.00	8/7/20	1:38:46 PM

@ratgdillon I used a TimeZones.csv file in my book DAX Cookbook, you can download it from here:

Chapter 3. Let me know if it helps or not, @ me in replies.

@Greg_Decklerthe dataset needs to link county or city to time zone. Listing the time zone and its time offset is helpful, but it won't be of any use if I can't link each row (city/state) to its corresponding time zone.

@ratgdillon I've never found a good list for this. Maybe find a list of the lat/long of each city. Get a similar list for the long of each time zone. Then you could create a calculation to figure out the time zone based upon each city's longitude?
