Great news. Thanks for the patch to base, Michael.
I tested this with zoneset("HST10"), zoneset("UTC0") and it worked as I expected on rtems 4.10.2.
I ran your test harness just now. Couldn't easily grab all the results, but I attached the epicsTimeZoneTest and the epicsSockResolveTest which failed 2 tests using strings in aToIPAddr(). Perhaps that's another setup issues with my board.

For rtems 4.9.6 (newlib 1.18.0) I have to set "HST10HST10" to get correct behavior. This is strictly speaking incorrect, and doesn't behave right on Linux. I've added cases to epicsTimeZoneTest which I'd ask you to check and try running (it's run as part of the usual rtems test harness executable).

Matt,
Could you try the attached patch for Base? It adds an iocsh function zoneset(). For US eastern time I can use 'zoneset("EST5EDT")' and see the change reflected in generalTimeReport().

Turns out access to NVRAM variables like epics-tz only work with MOTLOAD firmware (mvme-6100).On the PPC1-BUG firmware (mvme-2700) there isn't an obvious way.
For now, I'll have to define this in base/configure/CONFIG_SITE_ENV for each of our sites Hawaii and Chile.For Chile, this is a terrible situation. They can't make up their mind about standard time. They will be starting daylight saving time in May.So it looks like we'll have to rebuild EPICS Base each time their clocks change? Or choose a different BSP?
Can anyone confirm that the "epics-tz" variable is the preferred solution for the mvme-6100 (beatnik) BSP?
Thank you all for input!-Matt

Thanks. I just looked into this and src/RTEMS/base/setBootConfigFromNVRAM.c
Looks like the epics-tz variable is what I want.

You'll need to arrange a call to tzset() before anything happens.
http://man7.org/linux/man-pages/man3/tzset.3.html
Init() does this, but has probably already run. As I look at it, there
doesn't seem to be a good way to set TZ for the standard rtems app...
