doesn't support (for now) event-polling, the reason is that the Thunderbolt receiver the patch is written for doesn't support time-on-request, so you just have to sit there and wait for the time to arrive with the PPS. We tried to contact Trimble because there's presumably a firmware update that support it, but we didn't have much luck. 11372b15cb3dSCy SchubertHere is a link explaining the situation:<p> 11382b15cb3dSCy Schubert<a href="https://lists.ntp.isc.org/pipermail/hackers/2006-April/002216.html">https://lists.ntp.isc.org/pipermail/hackers/2006-April/002216.html 11399c2daa00SOllivier Robert <p></p> 11409c2daa00SOllivier Robert <hr> 11419c2daa00SOllivier Robert <p>Questions or Comments:<br> 11429c2daa00SOllivier Robert <a href="mailto:sven_dietrich@trimble.com">Sven Dietrich</a><br> 11439c2daa00SOllivier Robert <a href="http://www.trimble.com/">Trimble Navigation Ltd.</a></p> 11442b15cb3dSCy Schubert <a href="mailto:fernandoph@iar.unlp.edu.ar">Fernando P.
