How do I extract a timestamp from a network time server?

[instrument control]

Does anyone know how to extract a time stamp from a Symmetricom S250 Time Server using LabView or Matlab?  We need to get millisecond time accuracy.

Howdy,

I have never seen or used an S250 before. But, if you are connecting to it over Ethernet, I would try finding the S250 via data socket. Just open up a blank VI in LabVIEW and place a “DataSocket Select URL.vi” on the block diagram. Press run and you should be able to browse to the time data from the S250.

I’ll bet there are a lot of ways to connect to it with LabVIEW!

Charlie,

We'll try your suggestion and get back with you.  Thanks!!!

Dear Charlie,

We connected the Time server to a laptop with LabView 8.5 loaded on it and got the time server talking to the laptop.  We checked the IP connection using the ping command and also Internet Explorer and they both worked fine.  I did exactly what you suggested with the "datasocket select URL.vi" and typed in the IP address of the Time server into the IP start address box on the vi and nothing happened.  Do you have any other suggestions?  Thanks.

Open this VI (it was written in 8.5) and press run. You should be able to browse to something related to your time server (I don’t know what it will be) and read the data. This is not a matter of whether LabVIEW, Java, C++… or Matlab languages can get data from this time server, it is a matter of how.
