Argon Tank Date Stamp Question

When go fill tank they tell the date.
Most tanks need to be tested every 5 years.
Some new tanks well 10 years.

FYI the marks after the date [+*] is 10 years test date and over fill by 10%

I thought I knew how to read these, but I guess I don't. When was this tank tested?
