Your sketch is closest I've seen to what I'm looking for.

Just to make the request explicit:

I'm hoping someone can point me to a sketch, in Arduino IDE, that uses esp8266 to obtain NTP time.

Thanks all!

i used your code plus the ntp packet conversion routine from the example you had found, added code to capture the recv'd data and then made your code call the ntp server every 15s.
Output now looks like this:
AT+CIPSEND=48

> Seconds since Jan 1 1900 = 3637281585
Unix time = 1428292785
The UTC time is 3:59:45
AT+CIPSEND=48

OK

SEND OK
AT+CIPSEND=48

> Seconds since Jan 1 1900 = 3637281606
Unix time = 1428292806
The UTC time is 4:00:06

Thank you! Thank you! Thank you!

This code works!

I was also able, today, to finally flash to firmware version 002000902_NTP, and that allows direct query of NTP time using commands
AT+CIPNTP=(GMT offset)
and
AT+CIPNTP?

So I have two ways to do it!!!!

Thanks again.

- Tue May 19, 2015 8:00 pm #17912 The ntp.c works great, but I can't figure out how to run it as a subroutine. I only need to set the time once.
