I just found this online. A public service announcement. Copied from here:
South African Time explained: Just Now versus Now Now. Present Time: At this Time.
Relating to the current period of time, at this time… not to be confused with Right Now.
Right Now: Right Now.
More urgent than now with a higher probability of something actually happening. No guarantees though.
Now: Eventually, Maybe.
South African English is lekker but don’t be fooled by the word Now! Now spoken by a South African is more like the exact opposite of the word as we know it. If you’re told “now,” what the other person really means is maybe later, but definitely not now.
Basically almost not quite, absolutely now… maybe.
Now Now: Shortly.
A term widely used in South African conversations relating to the period of time which will elapse before the given task, time or oppotunity will present itself.
The actual word is derived from the Afrikaans ”nou-nou” (which can be used both in future- and immediate past-tense) idiomatically used to mean soon (sooner than just now in South Africa, but similar to just now in the United Kingdom).
It’s more immediate than Now, but still may never happen.
Just Now: Later.
If a South African tells you they will do something “just now”, they mean they’ll do it in the near future – not immediately, as in, “I’ll do the dishes just now.”
Realistically its an unknown amount of time… could refer to a few minutes, tomorrow or never.
