I have connect my Raspberry Pi to LAN but there is no internet available. Is there any method to update raspberry pi date time by using a PC (windows 7) in LAN? I want to get computer date and time to my Raspberry Pi when it is booting.

Remember that Raspberry Pi does not have real time clock. So even you are connected to internet have to set the time every time you power on or restart.

This is how it works:

  1. Type sudo raspi-config in the Raspberry Pi command line
  2. Internationalization options
  3. Change Time Zone
  4. Select geographical area
  5. Select city or region
  6. Reboot your pi

Next thing you can set time using this command 

sudo date -s "Mon Aug  12 20:14:11 UTC 2014"

More about data and time 

man date

When Pi is connected to computer should have to manually set data and time
