esp32: machine.RTC() function issue in ntptime.py

I think there is an issue with RTC in ntptime.py whenever i use this module it gives me either this error or no response. I tried it by removing the RTC functions and it worked fine. I am using Ethernet as my network with ESP32 DevkitC and LAN8720 module.

Code and Debug Messages:

>>>from machine import Pin
>>> import network
>>> l = network.LAN(mdc = Pin(23), mdio = Pin(18), power = Pin(17), phy_type=network.PHY_LAN8720, phy_addr=1)

Traceback (most recent call last):

I get no response maybe because settime() function isn't returning any value according to ntptime.py. When i downloaded the ntptime.py file and removed the RTC part and it worked.I also tried with the RTC part and just added return to the settime() function, it still gave me the same to errors.Here is the log with RTC part removed and return value added:

Here are the changes and i also added 19800 to get time in IST:

def settime():
   t=time()
   import utime
   tm = utime.localtime(t)
   return tm
