NtpTime

A simple NTP client. Keeps the Particle Photon Time synced to NTP. This should not be used for high precision time keeping. The Particle Photon Time is only one second resolution and hardware limitations prevent high accuracy setting. So the system time shouldn't be used for anything that needs more than accuracy to a large fraction of a second.

There is an interface that will return the time to millisecond resolution. Accuracy of that interface is primarily dependent on internet latency.

NtpTime uses one of the Photon's software timers.

ntptime's Issues

Core? Also CPP

Hi! Thanks for this. Should it work on a Particle Core? Also, bit confused where I define the server and which of the many CPP files I need. I'm used to there being a CPP file, a .H file and then code to use in your INO file. Here there seem to be lots of CPP files, a couple of .H files and a usage.ino. Any pointers on how to get started much appreciated! Thanks

It doesn't seem like this will update the time more than once

Hi,
am I missing something or is there a missing timer->start()? According to the particle docs: "a newly created timer is stopped"?

Also, in case of success you set synced to true but never reset it back to false in case of future failures?

And finally, according to the particle docs you need to call changePeriodFromISR instead of changePeriod since most of the calls should be happening from the ISR.

Time Zone

Hi.
How do I set up the Time Zone?

Thanks..
