util: Make TZ environment variable POSIX compatible 

`TZ='UTC'` is not a portable setting for the TZ environment variable.
POSIX says you’re supposed to use something like `TZ='UTC0'` instead.
Although `TZ='UTC'` works when GLIBC is used, this is not necessarily
true on other POSIX platforms. [1][2]
