2018-03-07 15:07:40 +0000 marked best answer why is my NTP client timestamp wrong?

This has been puzzling me for several hours now, and I'm pretty out of ideas. I'm modifying an embedded application to use NTP. I can send a request and get a reply (so I guess it's working), but my client timestamps show up in Wireshark incorrectly. They seem to be off by about 66 years, which makes me think it's related to how WS is interpreting my timestamp era, but my online research hasn't found anything.

I'd attribute this to a preference setting, except that the timestamps in the response are correct.

Thanks for any ideas... I realize that a snapshot would be very useful here, but I can't yet post images (or files).

Edit: posting a link to a file (hope I did this right):

Edit again: image file. Note the different interpretations of the transmit timestamp data:

Oops. sigh... It sucks getting old and having your eyes go south (that's my excuse anyway). Thanks, cmaynard. With

@jaap: done, and thanks.

Hi -

I'm sure this question has been asked and answered many times, but I can't find what I'm looking for.

I'm trying to apply filters so I only see traffic between two devices, and only when they're of UDP protocol. In the display filter, I use this:

(ip.addr == 192.168.70.20 || ip.src == 192.168.70.22)

and in Capture->Options, I've selected the (presupplied) udp filter. I'm still seeing traffic of other protocols, though. Can someone tell me what I'm doing wrong? Thanks.

Beautiful. That helps a lot. Thanks...I'd upvote you if I could.

Thanks for the response. The protocol I'm seeing that I don't wish to is NBNS. The communication between the two devices
