Time source & synchronisation
| Reference | GNSS/GPS satellite time (UTC) from a GNSS-disciplined PTP grandmaster — a Timebeat Timecard Mini with PPS, to ~4 ns. |
|---|---|
| Distribution | PTP / IEEE 1588 (Layer 2) to the hypervisor hosts, with hardware timestamping on the NICs. |
| Servers | Two independent stratum-1 NTP servers on separate hosts, for redundancy. |
| Accuracy | Nanosecond-order internally; sub-microsecond to GNSS/UTC as served. |
| Monitoring | Continuously cross-checked against ntp.time.nl, ntp.vsl.nl, time.cloudflare.com and time.google.com. |
