There is no locale called en-EG but what i want is to have english running but the currency be EGP instead of ج.م.

I basically need an english interface with local currency and time zone. Is that possible by setting cldr config ?

Peter, a language tag can convey quite a lot of information that isn't obvious at first. It is documented in the BCP47 'U' extension. Here's an example of using the en locale but with the Egyptian pound as the default currency and overriding the region to be EG.

# English but preferring Egyptian Pound, Egypt as the region and Egypt/Cairo as the timezone
iex> {:ok, locale} = Cldr.validate_locale("en-u-cu-egp-rg-egzzzz-tz-egcai")
{:ok, #Cldr.LanguageTag<en-u-cu-egp-rg-egzzzz-tz-egcai [validated]>}

iex> Cldr.Currency.currency_from_locale(locale)
:EGP

iex> Cldr.Locale.territory_from_locale(locale)
:EG

iex> Cldr.Locale.timezone_from_locale(locale)
"Africa/Cairo"

That said, I'm not sure what you mean by I basically need an english interface with local currency and time zone so If you have any examples of what you're trying to achieve I can provide more detail.
