Mmene Mungagwiritsire Ntchito Wothandizira Kusintha Mauthenga Awo Patsiku Lililonse 90
Mungathe kukakamiza wosuta kusintha malingaliro ake atatha masiku angapo mwa kugwiritsa ntchito lamulo ili:
sudo chage-90
Muyenera kugwiritsa ntchito sudo kukweza zilolezo zanu kuti muthamangitse lamulo ili kapena musinthe kwa wosuta yemwe ali ndi zilolezo zoyenera kugwiritsa ntchito lamuloli .
Ngati tsopano muthamanga kusintha -kulamulirani mudzawona kuti tsiku lomalizira likukhazikitsidwa ndipo chiwerengero chachikulu cha masiku ndi 90.
Mukhoza, ndithudi, kutchula chiwerengero cha masiku omwe akugwirizana ndi ndondomeko yanu ya chitetezo.
