Folks,
 
I have a problem and a question about EPICS time under vxWorks in 3.14.4.
 
Problem: The environment variable EPICS_TS_NTP_INET is supposed to allow me to specify the IP address of an NTP server.  My boot host (Windows) is not an NTP server, so I have used this environment variable to specify a valid NTP time server.  This works fine under 3.13.7.  However, when I boot the same system from 3.14.4 it does not work, I get an "iocClockSyncWithNTPServer: sntpcTimeGet S_sntpcLib_TIMEOUT error", and the "date" command says it's 1989.
 
Question: The environment variable EPICS_TS_MIN_WEST was used under 3.13 to set the timezone.  This is no longer documented in 3.14.4, and indeed does not work.  However, I could find no replacement variable documented either.  Typing "envShow" in 3.14.4 shows that there is now an environment variable TIMEZONE which seems to set the timezone.  Is this the correct way to do it, and if so what is the correct syntax.  The value on my system is set to:
TIMEZONE CUS::360:040602:102602
 
Does this mean Central US, minutes west of Greenwhich and the start and end date of daylight time in 2002?  If I want US eastern time this year what do I set this to?
 
Thanks,
Mark Rivers
