Kompyuta anayamba ndi powerengetsera (chilichonse purosesa akuthamanga powerengetsera): palibe bwino chizindikiro nthawi kapena digito kapena analogi, kapena zachilengedwe - kulibe. Nthawi zonse ndi ponseponse, koma mmene zikukambidwa ndipo n'komwe zimatengera mtundu wa pulogalamu, ndipo kuti ndi kofunika kwambiri pa nthawi, wautali basi momwe izo kulibe.

nthawi nzeru, amene ali mtengo kwambiri

Mu nthawi zosiyana za zinenero zosiyana ndi maganizo osiyana a nthawi Chinthu ndipo anali enieni tsiku mtundu. Koma ngati ife sititenga machitidwe zenizeni nthawi zakale, cholinga choyenera (mu misa, makamaka) wabwera posachedwapa.

Poyamba, mfundo ndi ofooka zimaonekera mapulogalamu. The Madivelopa anafuna kuchita ntchito, koma si nthawi zonse, kudziwa zambiri nthawi kanthu.
