There's a unix daemon called crond that runs commands at prescribed
times. Commands so run are said to run "from cron".

mod_perl will set a MOD_PERL environment variable, but there usually
isn't something called CGI. Various things such as REQUEST_METHOD,
GATEWAY_INTERFACE, and HTTP_METHOD are usual for detecting web
transactions.
