I would like to reboot now to fix this.

Can I proceed?

Hi Hugo,

Thanks 👍

I think it is best to put the following in the LERF linuxRT CPU's "kernel-modules.cmd"  file

# Use Eastern timezone.
# The computer hosting the linuxRT kernel is at JLAB
export TZ=EST5EDT
echo "Eastern timezone is "$TZ

Hi Sonya and Hugo,

Since LERF is a temporary facility with few linuxRT computers, we should just override "TZ=PST8PDT"  in "kernel-modules.cmd"

# Always use Pacific timezone. This will be fixed in future kernel images, but
# no harm in being redundant.
export TZ=PST8PDT
echo "Pacific timezone is "$TZ

Note: commonSetup.sh  is maintained by CVS.

I am not sure if it is worth the trouble to put logic that figures out the Locale/Region.

Hugo, can you tell us the order of all these start scripts?

I need a clear order of who calls who.

Starting from:  /usr/local/lcls/epics/iocCommon/lcls-llrfcpu01/startup.cmd

Hi Sonya,

Do you mind if I go in a fix this?

I will need to reboot both linuxRT computers.

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
