Update date time using batch file

For dual OS, sometimes windows show date incorrect. You need to go setting and force windows to synchronize its date time.
The easy way and fast is using batch files. Using text editor, create batch files for example datesync.bat in your desktop. Write or copy/paste this code:

Echo off
Echo Starting Windows Time Service
net start w32time


Echo Syncronizing Date Time
w32tm /resync
pause

Everytime your date show incorrect, run this script as administrator. It will start windows time service (should not be disable on services.msc) and syncronize date time from internet.

deb http://security.debian.org/ buster/updates main

# Main
deb http://kartolo.sby.datautama.net.id/debian/ buster main

# NON FREE
deb http://httpredir.debian.org/debian buster main contrib non-free

# BACKPORT

Note on error when running apt-get update:
E: Release file for http://kambing.ui.ac.id/debian/dists/buster/InRelease is expired (invalid since 265d 4h 18min 17s). Updates for this repository will not be applied.
use other sources e.q change "deb http://kambing.ui.ac.id/debian/ buster main contrib
" to "deb http://mirrors.kernel.org/debian buster main contrib"
