B4R Library TimeTools Library with NTP Time

Hello,

here is my first attempt to write a lib for B4R ;)

The Lib based on the following Libraries (you have to install this bevor you can use this lib):

https://github.com/aharshac/EasyNTPClient
https://github.com/PaulStoffregen/Time

for me it works fine in combination with the Software Real Time Clock https://www.b4x.com/android/forum/threads/software-real-time-clock.77158/#post-530071

i have Testet with the ESP8266 board

regards

Andy

I needed the # Days in the month so I could calculate holidays like Memorial Day, Thanksgiving, etc

This value was in Time.c but never saved in the the time structure.

I modified the Time-Master and rESP8266TimeTools to support this.

B4X:
                  Log("Days In Month:", mTimelib.getdaysinmonth(mTimestamp))

Sorry, but I do not understand, if I run out of Wi-Fi for a few minutes the clock keeps ticking and you can check the time, how?
