os.system set Timezone:based on ip in python code

 To set the system timezone based on the IP address using os.system in Python, you can follow these steps:

1. Get the location based on the IP address.
2. Determine the timezone from the location.
3. Use os.system to update the system timezone.

Here’s the Python code:

---

Install Required Libraries

bash
pip install requests timezonefinder

---

Python Code

python
import os
import requests
from timezonefinder import TimezoneFinder

def get_location_from_ip():
    """
    Get the approximate geographic location (latitude and longitude) based on the public IP.
    """
    try:
        response = requests.get("https://ipinfo.io/json")
        if response.status_code == 200:
            data = response.json()
            loc = data.get("loc")  # Latitude and Longitude
            return loc
        else:
            print("Failed to get location data from IP.")
            return None
    except Exception as e:
        print(f"Error: {e}")
        return None

def get_timezone_from_location(location):
    """
    Get the timezone based on latitude and longitude using TimezoneFinder.
    """
    try:
        latitude, longitude = map(float, location.split(","))
        tz_finder = TimezoneFinder()
        timezone = tz_finder.timezone_at(lat=latitude, lng=longitude)
        return timezone
    except Exception as e:
        print(f"Error: {e}")
        return None

def set_system_timezone(timezone):
    """
    Set the system timezone using the os.system command.
    """
    try:
        command = f"sudo timedatectl set-timezone {timezone}"
        os.system(command)
        print(f"Timezone set to: {timezone}")
    except Exception as e:
        print(f"Failed to set timezone: {e}")

def main():
    # Step 1: Get location (latitude and longitude) based on IP
    location = get_location_from_ip()
    if not location:
        print("Unable to determine location.")
        return

    print(f"Detected Location (Latitude, Longitude): {location}")

    # Step 2: Get timezone from location
    timezone = get_timezone_from_location(location)
    if not timezone:
        print("Unable to determine timezone.")
        return

    print(f"Detected Timezone: {timezone}")

    # Step 3: Set the system timezone
    set_system_timezone(timezone)

if __name__ == "__main__":
    main()

---

How It Works

1. Fetch IP-based Location:

   • The script uses https://ipinfo.io/json to get the location (latitude and longitude) based on the public IP address.

2. Determine the Timezone:

   • The timezonefinder library maps the latitude and longitude to a timezone.

3. Set the System Timezone:

   • The os.system command uses timedatectl to update the system timezone. This requires sudo privileges.

---

Example Output

plaintext
Detected Location (Latitude, Longitude): 23.8103,90.4125
Detected Timezone: Asia/Dhaka
Timezone set to: Asia/Dhaka

---

Notes

• Root Privileges: The sudo command requires administrative privileges. Run the script as a user with sudo access.
• Windows: The timedatectl command is specific to Linux. For Windows, you would need to use PowerShell commands via os.system.

Let me know if you need assistance adapting this for another operating system!

Step 2: Python Code to Handle Etc/GMT

You can map the Etc/GMT timezone to Windows-compatible names and set the timezone using tzutil:

python
import os
import platform

# Mapping of Etc/GMT to Windows-compatible timezones
ETC_TO_WINDOWS_TZ = {
    "Etc/GMT": "UTC",
    "Etc/GMT+0": "UTC",
    "Etc/GMT-3": "E. South America Standard Time",
    "Etc/GMT+5": "Eastern Standard Time",  # Equivalent to UTC-5
    # Add more mappings as needed
}

def set_windows_timezone(etc_timezone):
    """
    Map `Etc/GMT` to Windows-compatible timezone and set it on Windows.
    """
    if platform.system() == "Windows":
        try:
            # Map Etc/GMT to Windows timezone
            windows_timezone = ETC_TO_WINDOWS_TZ.get(etc_timezone)
            if not windows_timezone:
                raise ValueError(f"Timezone '{etc_timezone}' is not supported or mapped.")
            
            # Set the timezone
            command = f'tzutil /s "{windows_timezone}"'
            os.system(command)
            print(f"Timezone set to: {windows_timezone}")
        except Exception as e:
            print(f"Error setting timezone: {e}")
    else:
        print("This script is for Windows systems only.")

# Example usage
set_windows_timezone("Etc/GMT+5")

---

Output

For Etc/GMT+5:

Timezone set to: Eastern Standard Time
