To set up time synchronization, please check your computer's built in help to help you determine how to do this as it varies from operating system to operating system. Generally:

• On OSX, it is a matter of going to the system preferences and telling the Date&Time preference to 'Set Date and Time Automatically'
• On Windows:
  • you can follow these instructions to set the time sync in control panels. But note, that windows does this sync once a week, so it is still possible for your clocks to drift during the week.
  • If you want to actually force a time sync daily (or more often) you make a task that and follow the instructions in this help page
