Daytime
A network protocol used by devices for debugging and time measurement. A computer can use this
protocol to set its internal clock but only if it knows in which order the year, month, and day are
returned by the server. Not all servers use the same format.
Time
A network protocol for retrieving the current time from a server. The computer issuing the
command compares the time on its clock to the information returned by the server, adjusts itself
automatically for time zone differences, then calculates the difference and corrects itself if there
has been any temporal drift.
NTP
NTP stands for Network Time Protocol. It is employed by devices connected to the Internet in order
to obtain a precise time setting from an official time server. These time servers are accurate to
within 200 microseconds.
