An EnumTimeFormatsProc function can carry out any desired task. The application registers this function by passing its address to the EnumTimeFormats function.

This callback function can process enumerated data from custom locales. Data is not guaranteed to be the same from computer to computer or between runs of an application. If your application must persist or transmit data, see Using Persistent Locale Data.
