            Bug ID: 7432
           Summary: Update cron jobs on sa-vm1 to run at UTC and ignore
                    daylight savings change
           Product: Spamassassin
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sysadmins
          Assignee: sysadmins@spamassassin.apache.org
          Reporter: davej@apache.org
  Target Milestone: Undefined

The current jobs in sa-vm1:/etc/cron.d/automc are hard-coded based on the
current PST time zone just to get things rolling again after rebuild on new
server.  Need to setup best/reliable method to get this to continue to run at
the same time in about 5 months (Nov 5th).

From some basic research, the default cron on Ubuntu doesn't allow the CRON_TZ
entry like CentOS/RHEL's cronie does.  I am using cronie to run my day job 
masschecks server and it seems to handle everything perfectly.  I can put in
the desired TZ time and it figures it out:

[root@mail02.nsvltn cron.d]# cat runAutoMasscheck 
MAILFROM=noreply@ena.com
MAILTO=djones@ena.com
CRON_TZ=UTC
5 9 * * * vmail /usr/local/bin/runAutoMasscheck.sh

Ubuntu's cron is not so smart so we need to setup a solid method to run our
jobs.  It would be nice if we could install cronie on sa-vm1 but I don't think
that is going to be an option.

I have set the local TZ on the VM:

root@sa-vm1:~# timedatectl set-timezone UTC
root@sa-vm1:~# timedatectl status
      Local time: Wed 2017-06-14 21:50:52 UTC
  Universal time: Wed 2017-06-14 21:50:52 UTC
        RTC time: Wed 2017-06-14 21:50:52
       Time zone: UTC (UTC, +0000)
 Network time on: yes
NTP synchronized: yes
 RTC in local TZ: no

I ran "puppet agent -t" to see if it would change the TZ back and it seems to
be trying to set it to "Etc/UTC".  Anyway the TZ seems to be staying like we
want.

Then I adjusted the /etc/cron.d/automc entries to be the literal times we need
things to run so we should be good now.

--- Comment #1 from Dave Jones <da...@apache.org> ---
It would be nice to run the server at UTC to solve this problem and not have to
keep calculating file timestamp offsets when we run 'ls -l'.  We would need to
run this past the INFRA team.  I think they have Puppet managing the timezone
file but I am not sure.  We may want to try to change the system timezone to
UTC and see if Puppet puts it back to "America/Los_Angeles" then open a Jira
issue to ask the INFRA team about running the server at UTC.

I had been looking for options to let cron run as a different TZ without having
to make major changes. I will wait to see what INFRA says.

Let me ask informally first.
