Synchronisation of advanced computer networks is vitally crucial for a multitude of reasons, and thanks to the time protocol ntp (network time protocol) this is relatively aboveboard.
Ntp is an algorithmic protocol that examines the time on different computers and equates it to a single time allusion and adjusts each clock for drift to make sure synchronisation with the time source. Ntp is so able at this task that a network synchronised using the protocol could truthfully get millisecond accuracy.
Choosing the time source
In regards to establishing a time allusion there actually is no substitute than to find a source of utc (organized universal time). Utc is the worldwide timescale, applied all-round the world as a single timescale by computer networks. Utc is held precise by a constellation of atomic clocks all-round the world.
Synchronising to utc
The most firstborn method of receiving a utc time source is to use a stratum 2 internet time server. These are deemed stratum 2 because they distribute the time after firstborn obtaining it from a ntp server (stratum 1) that’s connected to an atomic clock (stratum 0). Unluckily this is not the most precise method of receiving utc due to the distance the info has to travel from host to the client.
