WRT to the archive, read docs/FAQ - it's available both through google and
at gmane.
WRT UTC, you need to fix up your settings. ntop uses the standard library
functions such as gettimeofday() time(), etc. these are converted to
localtime through (guess...) localtime() and localtime_r() (also
strftime()).
These are all standard C functions, which are sensitive (in varying degrees)
to the settings of timezone and locale.
So, if you setup your userid properly, it should automatically do the
conversions. I know that on many OSes the actual clock time setting (local
vs. UTC) and the resulting timezone settings are handled during
installation - you'll need to look at your OS docs for that.
Try playing with the test program below (gcc -g -o timetest timetest.c)
