I'll assume the last post told you how to install.
(Different distros have different install procedures).
I use Debian (apt-get ... which would save you needing
Red-Hat (rpm -- which also doesn't require compilation)
Don't know what you're using.
Once you think you have ntp, simply try (as root)
It uses file /etc/ntp.conf (And you need to put some
time-servers into ntp.conf, for you, you want the lines
Then read up and find some servers in Africa. (The defaults are all over the globe)
Once it's working, do
ntpq -p. You'll get the following:
remote refid st t when poll reach delay offset

LOCAL(0) LOCAL(0) 13 l 49 64 377 0.000 0.000 0.001
* Means current favorite + means computer thinks server is OK.
refid -- Source of where that server is getting time (could read GPS).
st -- Stratum (Tier 2 is good)
poll -- How many seconds between polls. Increases over time as accuracy
delay -- Time in seconds to get an answer
offset -- Error in time (in millisec ... thus 623564 is 623.564 seconds).
