SNTP - time zone

All,

We have used the System i as the SNTP time server for our internal network
for years now. Has worked flawlessly.

Our recently installed SAN (Cybernetics) has a spot to put in the IP address
of an NTP server. When the SAN sends an informational email, the timestamp
of the email itself is 5 hours different from the time in the actual
message. For example, en email received at 7:01pm has as the body:

Nov 14, 2009 12:01.20AM - Controller 4
INFORMATION - Verify started: unit=0

We're on Eastern Standard Time, which is GMT - 5:00. That is too
coincidental to me. Since the SAN has only a place to enter a time server,
but not a time zone, does it seem reasonable that the problem is in the
SAN? Firmware?

I learned today there is SNTP and NTP. But what little I read on it, I
don't think that would be an issue.

Thanks.
