If you are using the command prompt to set the time and type in the net time command you may receive the following message:

Could not locate a time-server.  More help is available by typing NET HELPMSG 3912.

If you are using a later version of windows such as 8.1 it is more than likely because the NET TIME command has been deprecated.

Net-Time-Could-Not-Locate-A-Time-Server

 

All you need to do is type the following in to the command prompt:

time

If you don’t want to be prompted to enter in a new time simply enter:
