// Parameters:
// [IN] nPaneID
// ID number of the bitmap resource of the whole clock.
// [IN] nBigID
// ID number of the bitmap resource of the big digits.
// [IN] nSmallID
// ID number of the bitmap resource of the small digits.
// [IN] bAlternateDateFormat
// TRUE to display date in mm-dd-yyyy format, else
// FALSE to display date in dd-mm-yyyy format.
//
// Return value:
// CLOCKST_OK
// Function executed successfully.
// CLOCKST_INVALIDRESOURCE
// Some error loading bitmaps.
// CLOCKST_THREADKO
// Failed creating worker thread.
