You should set the event.common.timestamp field before passing an event to SDL_PushEvent(). If the timestamp is 0 it will be filled in with SDL_GetTicksNS().
You should call SDL_CleanupEvent() after handling SDL_EVENT_DROP_FILE, SDL_EVENT_DROP_TEXT, SDL_EVENT_SYSWM, and SDL_EVENT_TEXT_EDITING. This cleans up the memory associated with those events, and you no longer have to free the data yourself.
