The issue with timestamps is probably the usual one - USA does dates in a very nonstandard way. The two logical and easily searchable methods are dd/mm/yyyy or yyyy/mm/dd, but US standard is mm/dd/yyyy which has least significant figure in the middle. Empeg being British made is probably sorting on year then month then date. Although it maybe isn't bounds checking, just figuring 17th month comes later than 10th month. The old hands I'm sure will correct me if I've got this all wrong
