[Wrf-users] Adaptive Time-step output times mismatch/incorrect

FYI, I've seen this exact issue with 3.2 also (and _only_ 3.2).  I've
had a couple emails with wrfhelp (the last being about a month ago), but
haven't heard back as to whether they were able to reproduce or
otherwise shed some light on this issue.  I expect they're busy.  But
I'll ping them again here.   ;-)

I've been planning to try a different set of compilers, and see if that
makes any difference.  But I've been busy too.

So, no help, but at least you're not alone.

It does look like the way you say. So, I suppose the issue is someplace
