I've just re-read this and got a bit confused by what you're trying to
say...

Shell and Perl scripts are both interpreted programs, they just use a
different interpreter (as defined by the hashbang at the top of the
script), similarly with things like tcl and expect, and god forbid -
python :)

Perl will access the unix clock using the same kernel system calls as
say, bash does.  I'm not sure I understand what you're trying to
differentiate.
