I have a question - what would be the best way to figure out in which timezone particular user is situated based on the location field data? It seems like considerable amount of users have this field populated with some data, the form, however, is far from being normalized.
While I am figuring out ways to normalize users locations and infer timezones, I wonder, if someone did it before and could share some experience, or maybe (ideally) there is some magic webservice which I can ask for timezones by a given location?
So far I am running through fairly simple process - tokenizing the field, sorting, grouping by frequencies and assigning timezones manually based on my best knowledge.
