display of time in web interface

[drw]

I notice that time-of-day display in the web interface is quite a bit behind the current (correct) time. I can synchronize the time with my computer and maybe an hour later the web interface is 5 minutes slow. If I log out of the web interface and then immediately login, then the time is back to being in synch with the computer. I don't know if this has any operational meaning but it can be confusing at times. (when looking at the times programs have run etc).

drw,

 

What version of ISY firmware do you have (Help->About)? This used to be a bug which has been fixed.

 

With kind regards,

Michel

v2.6 (latest?)

drw,

 

This is really odd! I just need to make sure that when you log back in the time is correct, right?

Yes, when I log back in the time comes back to the same as my computer time.

 

Just for the record, I am running the console in IE7 running in Windows XP which is being run in a Parallels virtual machine on my Mac/Leopard.

 

I have found that I like the ability to sort on a column in the Program Summary tab and so I have reverted to using Windows. I have not checked this behavior in OSX/Firefox combination. I will check and report back later.

drw,

 

Thanks. It's very possible that we have a Java cache issue here. Would you be kind enough to clear your Java cache as well?

 

With kind regards,

Michel

First, the Firefox running natively in OSX keeps time display perfectly.

 

I am confused about the clearing the Java cache. Are you talking about the cache in OSX? Or the one in Windows?

 

When I have the problem, I am running IE in Windows in a Parallels VM window. That would seem to indicate that it would be Java in Windows since the OSX Java is not involved. I can't find how to clear the Java cache in Windows. I've looked in IE settings and can't find anything about clearing the Java cache. There's a general clearing of temporary files.

 

I am also confused about how frequently the Java cache should be cleared. Hourly? Weekly? Every time I want to start up the administrative console? Reboot every time? Since this solution seems to be the source of many problems, it would be nice to know exactly how frequently it needs to be done.

[Michel Kohanim]

drw,

 

Great! This is good news ...

 

1. You might have to clear Java cache if and only if you've done a firmware update. Otherwise, there's no need whatsoever.

 

2. I have not used Windows in Parallel. Do you have Control Panel? If so, you should follow:

1. Control Panel->Java

2. Click on Settings (at the bottom)

3. Click on Delete Files (at the bottom)

Windows running in Parallels is all of the normal Windows. The Control Panel / Java is there.

 

I can't remember positively if the firmware updated or not. I believe it did (to 2.6). I got my ISY about 2 weeks ago.

 

Anyway, I did the Java Cache clear in Windows. After about 45 minutes of running the time in the administrative console is about 2 minutes behind the computer time.

 

This is not a big problem for me. It just made interpreting some of the program summary run times confusing. I now know that I should look at the computer time when checking program run times.

[Michel Kohanim]

drw,

 

Is it 2 minutes behind even in your MAC/Firefox? We need to make sure whether or not this is a bug (regardless of its severity).

In the "native" Mac/OSX/Firefox everything is fine. Time stays synchronized (over hours).

 

In the Mac/OSX/Parallels/Windows XP/IE time falls behind.

 

The only scenario I haven't tried is booting entirely into Windows (no OSX running) and trying IE. This would probably be the environment that most users are in. In order to do that I have to shutddown my whole Mac/OSX world. It's an experiment that I can do if you want.

drw, are you saying that in Parallels/Windows XP the clock is correct when you first open the interface but it slowly drifts behind the longer you leave the software open?

 

Micheal, am I right in assuming that the software gets the time from the ISY when you first open the interface then it just adds to it from there.

 

If I don't miss my guess, I bet time just isn't being kept quite right in Parallels.

[Michel Kohanim]

nstein,

 

You are right with the following addition:

The client keeps synchronizing with ISY every 5 minutes. But, the feature to keep synchronizing with ISY was only added in 2.6 and that's why I suspect a Java cache problem.

Yes, the time shown in the administrative console (in IE/Windows/Parallels/OSX) falls behind actual time as I leave the window open.

The time in OSX and Windows seem to be synchronized - they don't seem to differ - I have not seen OSX and Windows/Parallels have any time difference. But I will admit I haven't kept close watch on it.

At this very moment, OSX and Windows say the time is 6:43 and the administrative console is showing 6:41. The difference grows larger the longer the administrative console is left open.

As I have said before, if I logout of the administrative console and log right back in, the time is correct.

I have cleared the Java Cache in Windows(numerous times).

Michel,

I have watched the adm console time closely. It does look like the time is coming back into synch with operating system time every once in a while. So maybe your re-synch every 5 minutes is working. I am going to monitor more carefully for awhile.

[drw]

Michel,

The time in OSX and Windows seem to be always in synch. I have never seen them differ.

 

I see the time in the adm console in IE/Windows/Parallells/OSX fall behind frequently as much as 5 minutes.

 

I have seen the time come back into sync with real time (OSX/Windows). It doesn't seem to be on 5 minute intervals. My estimate its on a longer period that the correction happens (maybe 30 minutes?). The two cases that I have observed, the time got correct at about 25 after the hour and another case about 5 minutes after the hour.

drw,

 

Thanks so very much for the update and I would sincerely appreciate it.

 

With kind regards,

Michel
