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.

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

Thanks for any ideas...
