Incorrect time on Helicorder & .tar files

Technical Support
1

My helicorder is not showing local time and the UTC time is incorrect. I am connected to the server which I thought would synch the time, but it is still incorrect. Is there anyway to change the time?

Also, using Chrome for Mac when I “right click” on the trace the power spectrum is not displayed. Is there anyway to obtain this information?

Lastly, is there any software which can open and view .tar files that when the Download Data function is used?
Thanks!

A few questions:

  1. Can you upload your logs here so that we can take a look?
  2. Are you viewing the helicorders by clicking on the helicorders button on the web interface?
  3. Yes, there is a way to change the time, but most likely there is something preventing the Shake from setting its own time. Are you sure you had the Ethernet cable plugged in when it started up?

Are you right-clicking on the helicorders page I mentioned above? If so nothing will happen. This is a SWARM feature and as such will only work if you’re clicking on traces in SWARM.

Yes—try 7-zip: https://www.7-zip.org/

  2. Are you viewing the helicorders by clicking on the helicorders button on the web interface?
    I am viewing the helicorders using the web interface. Is there another way to view them. I click on the graph icon within my device’s interfaces.
  3. Yes, there is a way to change the time, but most likely there is something preventing the Shake from setting its own time. Are you sure you had the Ethernet cable plugged in when it started up?
    Yes, I used an ethernet cable plugged into my router when I set it up. Should I re-try that? RSH.RC35B.2020-02-12T18_02_38.logs.tar (1.1 MB)

Looks like 7-zip is just for Windows. I am able to uncompress the tar file but I can’t view it. When I try to open the file there is only machine code, no numeric values.

Ok let’s look at the log files first, then I will show you how to untar on a Mac:

  1. Interpretation of log files

    During the previous boot-up (postboot.log.old) you had stand-alone mode ON, which would explain the wrong time, since you did not have a GPS attached.

    The latest boot has stand-alone mode OFF, and thus NTP is running fine and the unit appears to have the correct time. Can you confirm this?

  2. Unzipping tar files

    Sorry, I missed that you mentioned you had a Mac in your first message. Macs have tarring/untarring software installed by default. Try this from a Terminal window:

    # first, change directory to where you downloaded the logs
cd ~/Downloads
# then use the tar command with these options (x,o,p,f, and t)
tar xopft RSH.RC35B.2020-02-12T18_02_38.logs.tar

    The files should appear in whatever folder your tar file is in (I assume Downloads). If you’d like them organized a little better it might be wise to create a new folder inside Downloads, move your tar file into there, cd into that folder, and then use the tar command above.
