Essentially, play with the API making the timezone values further and further imprecise. Compare against most precise value (from geolocation api in browser) and assert quality. Ideally, if lat/lon can be generalized to 1 or 2 precision points, additional google api call needed would be minimized.

This SO answer has more detail.

Rely on ptyz's .astimezone(timezone(TZ_ID)).dst() == timedelta(1) to determine if in DST or not. This will allow for much longer cached timezone api calls to google (cache the timeZoneId field - stored as TZ_ID in the line above - from response for 2 weeks or something).

Also, set the timestamp param in google maps timezone call to 0. Response is dst-unaware:

{
   "dstOffset" : 0,
   "rawOffset" : -18000,
   "status" : "OK",
   "timeZoneId" : "America/New_York",
   "timeZoneName" : "Eastern Standard Time"
}

Note the dstOffset is 0.
