    <p>I have a python script that is essentially a small socket server that does some simple network tasks for me, and I started running it as an upstart service to keep track of it and manage whether or not it was running. To log information, I am using Python's built in logging module. When running as an Upstart service, I noticed a small problem: All of the time calls come out in GMT. When running it on its own(either <code>./scriptname.py</code> or <code>python scriptname.py</code>) it uses local time, and Python is aware of the local time. The system time is set correctly, and I only see this behavior when running as an upstart service. Does anyone know why this would happen and how I could fix it?</p> <p>EDIT: Relevant code: I have a helper class, conveniently called helper, that contains some oft used functions (I know it needs to be better organized, but it was thrown together fairly quickly). Most notably this function that I use to set up my logger:</p> <pre><code>class helper: log_format = '%(asctime)-25s %(name)-25s %(levelname)-12s %(message)s' @staticmethod def createLogger(name): rotatingFile = logging.handlers.RotatingFileHandler('/var/log/myLog.log', maxBytes=1048576, backupCount=5) rotatingFile.setLevel(logging.DEBUG) formatter = logging.Formatter(helper.log_format) formatter.time = localtime() rotatingFile.setFormatter(formatter) log = logging.getLogger(name) log.setLevel(logging.DEBUG) logging.basicConfig(format=helper.log_format, level=logging.DEBUG) if not log.handlers: log.addHandler(rotatingFile) return log </code></pre> <p>And it gets used like this in one of my classes:</p> <pre><code>class MyClass: def __init__(self): self._log = helper.createLogger('LogName') self._log.info('Some relevant info') _log = None </code></pre> <p>It's all pretty straightforward use of the python internal logging tools. I added the <code>formatter.time = localtime()</code> after I started noticing this problem, but before I realized that it only happened when run as a service. It didn't help.</p> <p>Here is my (very basic) upstart config that I got from a tutorial:</p> <pre><code>description "Blah blah" author "My Name &lt;My Email&gt;" start on runlevel [234] stop on runlevel [0156] exec /path/to/script.py respawn </code></pre>

    1. COIn your upstart config, is the TZ environment variable being set?

    2. COI actually added it to the upstart config to see if that would work but it didn't do anything. I'm new to upstart but I tried `exec TZ=/usr/share/zoneinfo/US/Central` and `exec export TZ=/usr/share/zoneinfo/US/Central` but it still has time in GMT when I restart the service.

    3. COMaybe post your sample code so we can experiment with it? I assume if you run it while logged into a guest session that it also works properly with local time?

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
