Arguments: date-time defaults &key copy
This function returns a date-time object constructed by filling in any
unsupplied components in date-time
with the corresponding
values from defaults. Both date-time and defaults
must be date-time
objects.
When copy is true a new date-time
instance is created. When
copy is false (the default), the
date-time argument is overwritten with the return
value.
