I'm using I'm not using Stratum-1 servers (since I read that they
shouldn't be used by individuals), but stratum-2 so they are lower
quality, but I have few of them in the list, can just one of 
them affect my time that much?

Here is my /etc/ntp.conf:

driftfile /etc/ntp.drift
# Los Angeles, CA
server gandalf.theunixman.com
#Los Angeles, CA
server 66.92.40.210
#Los Angeles, CA
server ntp2.sf-bay.org
#Riverside, CA
server hydrogen.cert.ucr.edu
#Los Angeles, CA
server clock.develooper.com

Also I didn't saw any ntp messages in clock around that time.

Perhaps you're right that NTP could be blamed for it, but it's little
suspicious that it happen when sendmail was sending mail (I'm
apologizing, that I forgot to mention that before):
