Let me asume you use a _recent_ mkisofs and set up a correct timezone...
Then you found a FreeBSD kernel bug in your filesystem code.
BTW: The first bug I found in mkisofs (this was in 1995) was a TZ bug and
mkisofs did use the wrong sign for the timezone offset. Since this has been
fixed, the only reported problems where in effect +- 24 hours from New-year.
What do you get from "mkisofs -version"?
What timezone do you have (how many hours from GMT and which location)?
What do you have in the TZ= variable?
What do you see with "TZ=GMT ls -l ToJoe"?
