After switching to
const timeSync = NtpTimeSync.getInstance();
works, however, I would like to use different NTP servers.
Thanks, very cool library :)
I believe the hard-coded 3
here is what would need to be configurable:
ntp-time-sync/src/NtpTimeSync.ts
Line 171 in 70be15b
Let me know what you think.
We're seeing a lot of this in our CI:
Connection error: Unable to get any NTP response after 3 retries
Hey there,
I ran into an issue trying to install this module with the latest LTS version of NodeJS. Here's the error message I got:
error [email protected]: The engine "node" is incompatible with this module. Expected version "^14 || ^16 || ^18". Got "20.10.0"
Any chance we could get support for NodeJS 20?
Thanks a bunch for your work!
I am getting the below error from past 2 days. This module was giving correct result one month back.
Error: Connection error: Unable to get any NTP response after 3 retries
at NtpTimeSync.collectSamples (vendor.bundle.js:119319)
Got this error when tried to use ntp-time-sync dependency
Error output:
error [email protected]: The engine "node" is incompatible with this module. Expected version "^12 || ^14 || ^16". Got "18.12.1"
Hi,
I'm getting the following error:
This dependency was not found:
* dgram in ./node_modules/ntp-time-sync/dist/index.js
To install it, you can run: npm install --save dgram
Same error after installing dgram. Looks like it's related to the fact that dgram is not longer a project on npm.
Thanks
