Ideally, sites should have NTP running from boot so that time is always accurate.  If 
admins refuse accurate time <G> then the script should be modified to check to 
see if ntpd is running before invoking ntpdate (which will fail if ntpd is running 
anyway).

But yeah, don't ever assume cron has the right path.
And while we're at it, at least one of the time servers included in the 6.8.0 distro failed to resolve: 
[ldm@bigbird ~]$ ldmadmin start

Couldn't get time from time-server at terrapin.csc.ncsu.edu using
the ntpdate(1) utility, "/usr/sbin/ntpdate".  If the utility is
valid and this happens often, then remove terrapin.csc.ncsu.edu
from variable "@time_servers" in the configuration-file,
/usr/local/ldm/etc/ldmadmin-pl.conf.

terrapin didn't resolve with a manual 'host' query, either.
And, since I'm running ntpd, ntpdate can't get the socket... and ldm isn't the root user (but I can always fix permissions).
I like the idea, however, of forcing a whine at startup to make folks think about setting up ntpd. 

Now to go back and tweak my script.

Couldn't invoke the ntpdate(1) utility, "ntpdate": No such file or
directory.  Set the value of the variable "$ntpdate" in the
configuration-file, /home/ldm/etc/ldmadmin-pl.conf, to the

pathname

of the ntpdate(1) utility.

You should either fix the problem (recommended) or disable
time-checking by setting the variable "$check_time" to 0 in the
configuration-file, /home/ldm/etc/ldmadmin-pl.conf, (not
recommended).

Turns out that the answer is that RHEL and CentOS don't

have paths for

/usr/sbin in their default .login or .bashrc files. Putting them in
there, or putting an absolute path into the ladmadmin-pl.conf entry
easily fixes the issue.

Otherwise, LDM 6.8.0 is working great.

Hmmm. Steve, I'd recommend adding the absolute path in the default
ldadmin-pl.conf.  I'll explain Tuesday.
