NTP charms survey
This survey is designed to find out how many people are using the NTP charms and for what purpose. I'd like to know how important the NTP charms are in our ecosystem, and how useful it would be for them to be more self-configuring, based on the constraints of the environment.

Your answer
What maximum time offset are you aiming for?
< 0.1 ms - for a timing-critical application
