man ntpdate:
"
-s Divert logging output from the standard output (default) to th=
e
system syslog(3) facility. This is designed primarily for
conve-
nience of cron(8) scripts.
"
Change your cron job to
5 * * * * /usr/sbin/ntpdate -s ru.pool.ntp.org
This will suppress the email you're getting. Consequently, this doesn't
solve the problem of not finding a suitable time server, but for that I'd
suggest enabling ntpd. You should do some reading ('man ntpd') or more
specifically, if you don't want to leave ntpd running, read-up on 'ntpd -q'
which mimmicks the behavior of ntpdate but allows you to use multiple ntp
servers.
