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!
