ntpclient's Issues

First NTP sync is wrong

Hej

I am testing your code on a SonOff Th10 but I have a slight problem the first sync gives me the wrong time.

Serial print follows

`MDNS responder started
HTTP server started
....Got IP: 192.168.1.21

Got NTP time: 1970-01-01T00:00:08 last sync 1970-01-01T09:00:02
Got NTP time: 1970-01-01T09:01:02 last sync 2018-01-08T14:57:02
Got NTP time: 2018-01-08T14:58:03 last sync 2018-01-08T14:58:04
Got NTP time: 2018-01-08T14:59:05 last sync 2018-01-08T14:59:05
`

I have changed to print out the current time also.

`
case NTP_EVENT_SYNCHRONIZED:

Serial.printf("Got NTP time: %s last sync %s\n", NTP.getTimeDate(now()), NTP.getTimeDate(NTP.getLastSync()));

break;`

Any ideas whats going on. The NTP server works when using regular ntpdate so thats not the issue.
I was thinking maybe I could force the update in setup but gettime is private so that is not an option at this stage.

Not possible to install the library

Dear Sir,
I have Arduino IDE 1.6.9 installed at Windows 10 laptop, and I tried to install your library both with the manual way ( download,, extract / rename the unzipped directory as NTPClient and transferred to the appropriate library directory ) and the Arduino "Add .ZIP library ..." way, both without success unfortunately... In the "Add .ZIP library ..." I got the following error: "Specified folder/zip file does not contain a valid library"

and in the manual way invalid library as well.

Please guide me what is wrong...

Thanks and Best Regards,
Mike Kranidis

P.S. Sorry, I forgot to say a BIG THANKS for your fine as I can understand library (sorry not possible to run it yet...!)

How to use local IP

Hi,

NTPCLient.ino doesn't free the char buffer allocated inside NTPClient::getTimeDate

The example program NTPClient repeatedly calls const char *NTPClient::getTimeDate(time_t tm).
This method allocates a char buffer and returns a pointer to this buffer to the caller.
NTPClient.ino should free these pointers but doesn't.
The (demonstrated) result is that 24 bytes of the heap is lost on each call of getTimeDate () and the program finally crashes.
