Cron is usually started at system boot -- I can only assume that
/etc/profile is not read by the shell firing off the "init.d" scripts. 

You can view a process's environment with the BSD version of ps(1) and
specifying the "e" flag.

   % /usr/ucb/ps aexwww | grep cron
   155 ?      S  0:01 /usr/sbin/cron PATH=/usr/sbin:/usr/bin TZ=US/Pacific

On my Solaris 2.5.1 system, all 'cron' is for an environment is:
    PATH=/usr/sbin:/usr/bin
    TZ=US/Pacific
