Request: display timezone on Job Status page

[avni]

To make it easier for the user to troubleshoot and trace installs, placing a request to add timezone to:
Admin Console -> Utilities -> Display Job Status -> In the "Sched/Elapsed" column of the table

A user can alternatively get the timezone from the command line of their iiab install via timedatectl, but having it in the UI would remove this extra step. Thank you in advance! :-)

FYI @avni this was discussed during today's IIAB community call at http://minutes.iiab.io

FYI @tim-moody is also considering several refinements to:

1. Make the famously large table (at http://box.lan/admin > Utilities > Display Job Status) more readable on smaller screens, and also...
2. Somehow include the complete output of the job (instead of just the last 10 lines from tail) within the Result column, as @jvonau and I have requested.
