I think that WIN32 does provide this routine -- at least my quick
check with google seems to imply this.
The vxWorks case is a little trickier. I suppose that someone out
there actually uses the IOC shell rather than the vxWorks shell.
What's' your feeling on weak references?
How about an epicsTzset() macro in some os-dependent header. This
would do nothing on vxWorks and expand to tzset() on all others.

Since we're on the topic of time, I'd like to propose the
following change to the IOC shell. This is in the handler
function for the epicsEnvSet command.

epicsEnvSet (name, value);

+ tzset();

}
This will ensure that changes to the TZ environment variable (in
an st.cmd file, for example) actually have an effect.
That change is not portable; according to my reference manual
vxWorks doesn't have a tzset() routine, and I have similar doubts
about WIN32. Maybe the correct solution would be to register an OS-
specific command that can set the IOC's timezone data?
