There was another thread here about a confusing Julian date system for Escalon labels which I can no longer find.
But for those of you interested, you guys can forget about the julian calender stuff. I just talked to the people at Escalon about the can of 4-in-1's I purchased recently. Turns out the can was from 2003 and my reputable grocer had no idea they were selling old stock. Escalon has contacted my grocer to discuss the old stock

Anyway, as of 5/01/05 they no longer use julian dates. The first number in the second string is now the year packed.
So for can code FRES3 6H18J;
FRES=Product (6-in-1)
3= production line (line 3)
6= Year (2006)
H= Month (H is 8th letter of alphebet/August is 8th month)
18= Day (18th of August)
J= Time (She did not tell me how to decipher this but it might be 10am since J is 10th letter of alphebet).
Hope this clears things up for you all.
