##Synching date & time in Unix and Windows

At times, we might need to change the system time for working on some developmental and testing activities. Setting a new time is always easier, and pretty straight forward in many operating systems.

Have you ever wondered how to reset / resync the correct timestamp.

Yes, I thought so. We will try setting it back again to the correct time, instead of re-synching with the time server. Resetting the time using a time server is pretty easy, and you can do that just in a couple of steps, stated below.

Unix - (Ubuntu Flavour)

• First set the date to a different date with this command

date -s "10 Sep 2013 15:59:59.000-UTC-0700"

• To sync the time back to correct time stop the ntp service by executing this command

$ sudo service ntp stop

• Now map the time server like thisl ntpdate -b pool.ntp.org (you can use any other time server)

• Start the ntp service back again sudo service ntp start

Windows - (Windows 8)

• Click the date from the taskbar.

• Now click Change Date & Time Settings

• Under Date and Time tab you can change the current system time using the Change date and time option

• When you want to resync, navigate to the Internet Time and click on Change settings... button.

• In the opened pop up window, select the server you want to use for synchronization and click Update now button.

• This will show the running status of the synchronization. Once the date and time are synchronized you can click on ok and close the window.

Hope this helps - Sharath
