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);
+    if (strcmp(name, "TZ") == 0) {
+        extern void tzset(void);
+        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?
