Hi Wes,
Can you set the timezone parameter in your DHCP Config for the Linux RT CPU section?

Please use this for JLAB ===> option posix-tz-string "EST5EDT,  M3.2.0, M11.1.0";

Snippet from what we have here at SLAC:
--- dhcp.conf snippet ---------------------------------------------------------------------
# =========================================== 
# Let's set time zone for linuxRT CPUs 
# =========================================== 
option posix-tz-string code 100 = text; 

# ----------------------------------------------------------------------------- 
# client device definitions 
# ----------------------------------------------------------------------------- 
group { 

# =========================================== 
# # Let's set time zone for linuxRT CPUs 
# # ===========================================   
option posix-tz-string "PST8PDT,M3.2.0,M11.1.0"; 

 if exists user-class and option user-class = "iPXE" {

Cheers,Ernest

Yes we will need to deal with that soon.
The DHCP server also had a TZ configuration that Wesley was going to address... @Wesley is this fixed after moving the dhcpd.conf to your dhcp server?

Cheers,
Hugo

    Hi Hugo,

    I see commonSetup.sh sets the time zone to SLAC time:

    export TZ=PST8PDT

    How do we want to handle this?

    And actually, the linuxRT CPU system time is 8 hours ahead:

    #date
    Thu May 17 22:19:05 PDT 2018

    so that is odd.

    Thanks,
       Sonya
