Hi,
I think only if you have a business requirement for scientifically accurate time such as nanosecond or picosecond-level synchronization You may want to consider PTP, Otherwise NTP should definitely suffice for your business.
NTP Servers
An NTP server is directly connected to a highly accurate timekeeping source, like the GPS satellite network that orbits the Earth. The server receives time information from the GPS satellites, uses algorithms to process the information, and then broadcasts it to all devices on the network that are requesting time information. NTP servers like our TM1000A can synchronize clocks and other local network devices with nearly millisecond accuracy, which suits most business and industrial needs for time serving accuracy. However, if greater than millisecond synchronization accuracy is required, a PTP server might be the best bet.
PTP Servers
PTP is another network-based time synchronization standard, but instead of millisecond-level synchronization,
PTP networks aim to achieve nanosecond- or even picosecond-level synchronization.
For most commercial and industrial applications, NTP is more than accurate enough, but if you need even tighter synchronization and timestamping, you'll need to migrate to a PTP server.
PTP timestamping so accurate because It uses hardware timestamping instead of software, and like any other fine scientific instrument, PTP equipment is dedicated to one specialized purpose: keeping devices synchronized. For that reason alone, PTP networks have much sharper time resolutions, and unlike NTP, PTP devices will actually timestamp the amount of time that synchronization messages spend in each device, which accounts for device latency.
