This object lets an admin manually specify an assumed clock class, 0 to 255, for an input PPS port, and is only an informational read-out rather than settable when the port is configured as output. This is useful when the actual incoming clock class isn't automatically conveyed, letting the admin declare what quality to assume for downstream calculations. For example, if a PPS input comes from a GPS receiver that doesn't signal its own clock class electronically, the admin manually sets f3PulsePerSecondPortAssumedClockClass to reflect the known GPS-grade accuracy.
