I am in South Africa with my girlfriend. We have been traveling around the world for 5 months and have another few moths left. We are thinking to take the next two months, buy / rent a truck and drive up from south africa, through Namibia, Botswana, Zimbabwe, Mozambique and then to Tanzania.
The Standard C tuning (sometimes referred to as Re-entrant tuning) is the most common ukulele tuning for soprano, concert and tenor ukes.
So, being thorough, the exact standard tuning of the guitar is the one you mentioned, which is: E2 A2 D3 G3 B3 E4. Îs it has been mentioned in the comments, the guitar music is written one octave above than it's played. So, you wouldn't see guitar music in the bass clef.
