A python script to update time in Windows using HTTPS, when NTP is not working. Works on scraping duration since epoch time from www.unixtimestamp.com and uses win32api (earlier pywin32) to update the system time. Needs to be run with administrator permissions.

update_time.py

import requests
import datetime
import win32api

page = requests.get('https://www.unixtimestamp.com/', headers={'Cache-Control': 'no-cache'})
text = page.text


for line in text.split("\n"):
	match_text = "<h3 class=\"text-danger\">"
	suffix = " <small>seconds since Jan 01 1970. (UTC)</small></h3>"
	if match_text in line:
		line = line.replace('<',' ').replace('>',' ')
		epoch_time = [int(s) for s in line.split() if s.isdigit()][0]
		break

utcTime = datetime.datetime.utcfromtimestamp(epoch_time)

try:
	# SetSystemTime takes time as argument in UTC time
	win32api.SetSystemTime(utcTime.year, utcTime.month, utcTime.weekday(), utcTime.day, utcTime.hour, utcTime.minute, utcTime.second, 0)
	localTime = datetime.datetime.fromtimestamp(epoch_time)
	print("Time updated to: " + localTime.strftime("%Y-%m-%d %H:%M"))
except:
	print("Could not update time")
