Will have that in shortly.  Do I need this also?

option posix-tz-string code 100 = text;

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

Hi Sonya,

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
