What is the difference between GNSS and GPS? What is a stratum level for time server structures? What is Leap Seconds and what is its technical significance?

DTS

Do MOBATIME time servers support IRNSS / NavIC? What is GIDAS Embedded and how does it enhance the security of MOBATIME time servers? How to perform the initial commissioning of a DTS device (without DHCP)? What is it about DTS time servers communicating via an “optical link” with a redundant structure? What mechanisms are there at the DTS device level to safely deal with these leap seconds? What is the typical response time when a client requests the time from a DTS device? Calculation of heat dissipation for master clocks?

NTP

What does the “Requests per second” key figure mean for the number of clients in the network that a time server can synchronize? NTP Network Bandwidth for synchronization? Why do you need your own NTP server although there are NTP servers available on the internet? What is the difference between NTP and SNTP? Why does my Windows Time Service not synchronize with my NTP Server?

PTP

What are PTP profiles? What is PTP (IEEE 1588)? Do you need PTP or is NTP better suitable? What does PTP mean, will it replace the NTP procedure in the future?
