time.py

# Get time stamp information from any server with a Web Server running
# using HTTP protocol. Comes in handy if I connect to a Wifi
# connection that redirects me to a login webpage, even I do not have
# the credentials to get a real Internet connection, I can still get
# the time information from that server, through Wifi.
#
# Usage: time.py [URL ADDRESS]
#
# Examples: time.py https://10.10.1.1 or time.py http://192.168.10.1:5001
#
# Ip address of the web server could be the Default Gateway address
# -see the output of ifconfig or ipconfig, or route print, or nslookup-
# or simply be retrieved from your browser by copy and paste.
