nwts has a lot of potential to be more than a simple GPS emulator just to set the time from UTC.
There were several requests from customers to extend nwts' functionality.
Last week we released nwts version 2.1 beta. This version includes:
Some customers requested the "Clock drift correction" option:
Two clocks from my customer Jeff Walton: on top there's a Nocrotec Bluedream and on the bottom a PV Electronics clock. The Bluedream clock has a constant delay of -3 seconds, so when connecting the clocks to the same time source, there's always a noticeable 3 delay on the Nocrotec displayed time.
Changing the drift in nwts on the unit that has the delay, increasing it to 3 seconds, makes the Nocrotec clock align the time with the PV Electronics clock.
Here's Jeff's configuration. You can also see the time zone and DST parameters.
The release version of nwts 2, version 2.2 will be available on Sunday, April 2nd 2017. All new nwts units ordered after this date will include version 2.2.
