Data Connectors: Import culture - what is it?

[Jscarbs]

Hello,

I'm figuring out optimal settings for CSV imports and noticed there is something called "Import Culture" which i typically leave blank.  There doesn't appear to be documentation on what that field does or when it should be used.  Any thoughts?

Thanks!

Typical import culture  "de-DE"      ,    "en-US"    ,    "zh-CN"
