If like me, you keep an eye on the Mac OSX activity monitor, then you’ve likely seen ntpd and wonder what the heck it is.
NTPD is the Unix (or in this case Macintosh OSX) Network Time Protocol Daemon. NTPD is the service that your Macintosh computer uses to keep the time up to date (assuming you are using the system default setting – Set Date and Time Automatically). Occasionally your Mac will ask time servers on the Internet for the current time and adjust your clock and calendar appropriately. Of course this assumes you have active Internet Connection.
Setting the Date and Time automatically in Macintosh OSX System Preferences
Of course, you can always disable this by unchecking the box. This will remove NTPD from memory and your Mac will no longer get automatic date and time updates. This is however, not recommended.
