Good to know. Could you explain what you mean by "caching per locale"?

The current code for to_char will on the first call to to_char build arrays with the localized names of the week days and the months. I suspect that you may need to build something similar but a set of arrays per locale.

See the DCH_to_char function and its call to cache_locale_time.
