- Must be zero.
A pointer to a SYSTEMTIME structure. If DTM_GETSYSTEMTIME returns GDT_VALID, this structure will contain the currently selected time. Otherwise, it will not contain valid information. This parameter must be a valid pointer; it cannot be NULL.
Returns GDT_VALID if the time information was successfully placed in lParam. Returns GDT_NONE if the control was set to the DTS_SHOWNONE style and the control check box was not selected. Returns GDT_ERROR if an error occurs.
