Re: Daylight savings time

[Eric Norum <norume@aps.anl.gov>]

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.

+        tzset();

}

This will ensure that changes to the TZ environment variable (in an  
st.cmd file, for example) actually have an effect.
