Thanks for reporting this. I fixed the bug by installing the attached 
patch to emacs-25.

By the way, the value "UTC" is not portable to non-GNU systems, and 
POSIX says that in theory it could cause Emacs to crash. The value 
should be "UTC0" or (in Emacs 25) t. I see that some of Emacs's own 
source files have this issue, and plan to look into that.
