Setting Linux Timezone from the Shell

Assuming you've got NTP, etc set up, your issue shouldn't be any more complicated than

1. Setting it properly in /etc/localtime:

cp /etc/localtime /etc/localtime.ORIG; 

cat /usr/share/zoneinfo/America/New_York > /etc/localtime 

2. Change /etc/sysconfig/clock to

ZONE="America/New_York" 

UTC=true 

ARC=false 

No OS restart is required, but it's probably a good idea. Any process with a JVM almost certainly needs one, though.

Note that the original localtime file is backed up in the line above, in case you need it.

Forgot to screen?

Sometimes even the best of us forget to invoke screen prior to running a long job.

I found an excellent workaround on serverfault (http://serverfault.com/questions/55880/moving-an-already-running-process-to-screen) that I'll repost in case it vanishes.

Simply put, you detach the process from your login shell using "disown".

So,

cntl-z

bg

jobs

disown -h %jobspec-id-from-jobs

And just like that, you've bullet-proofed it from a sighup. Kill your shell and pack up for the night because it'll run to completion.
