[Lerftest-ctrls] linxuRT CPU system time

[Williams Jr., Ernest L.]

Hi Guys,


For the linuxRT machines, please use the following for the East Coast:


export TZ=EST5EDT


Eastern Standard Time is 5 hours earlier than Coordinated Universal Time (UTC). Standard time and daylight saving time both apply to this locale.
By default, Eastern Daylight Time (EDT) is one hour ahead of standard time (that is, EDT4).
Since it isn't specified, daylight saving time starts on the first Sunday of April at 2:00 A.M., and ends on the last Sunday of October at 2:00 A.M.





Cheers,

Ernest Williams

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
