Funny, I've just recently been looking at this code.
I think that the issue is in the DTK_TIME handling code in DecodeDateTime().
For this input string the "T" is recognised as the start of an ISO
time, and the ptype variable is set to DTK_TIME. The next field is a
DTK_TIME, however, when it is handled it doesn't reset the ptype
variable.
When it gets to the timezone "America/Chicago" at the end, this is
handled in the DTK_DATE case, because of the "/". But because ptype is
still set, it is expecting this to be an ISO time, so it errors out.
The attached patch seems to fix it. Could probably use a new
regression test though.
