6 results about "Timekeeper" patented technology

In general, certain embodiments described herein relate to a method for managing timing in a system. The method includes synchronizing a first TS of a global timekeeper with a global TS of a global positioning system (GPS) satellite. The method then transmits a first timestamp at a first point of time from the global timekeeper to a primary baseboard management controller (BMC). The primary BMC includes a second TS and the first timestamp is transmitted using precision time protocol (PTP). The primary BMC and the global timekeeper exchange three other timestamps which the primary BMC uses to calculate an offset time between the first TS and the second TS. The primary BMC then synchronizes the second TS with the first TS using the offset time.

A system (30) for controlling, regulating or authenticating a timer comprises means (31) for measuring the frequency signal and / or rate of one or more timers based on a time reference provided by an optical atomic clock (10) comprising an atomic vapor chamber (1), the atomic vapor chamber (1) comprises a hermetically sealed enclosure (8) defining a volume containing a vapor of a reference atom (2), the hermetically sealed enclosure (8) comprising an optical inlet (3) allowing transmission of a probe beam adapted to excite an optical transition of the reference atom (2) and an optical outlet (4) allowing transmission of a fluorescence signal from the reference atom (2), the hermetically sealed housing (8) further comprises a wall (5) through which the fluorescent signal can penetrate, said wall (5) being coated on its outer side with a coating (6) which is reflective to the fluorescent signal.

Techniques are provided for improved precision timekeeping for a global positioning system (GPS) receiver. A methodology implementing the techniques according to an embodiment includes generating a system clock signal at a reference frequency, the system clock signal having a first frequency stability. The method also includes generating an auxiliary clock signal at an auxiliary clock frequency, the auxiliary clock signal having a second frequency stability that is greater than the first frequency stability, wherein the auxiliary clock frequency differs from the reference frequency by a frequency offset. The method further includes calculating corrections to the auxiliary clock signal based on a measure of error in the frequency offset and on an estimate of error in the auxiliary clock frequency. The method further includes using the calculated corrections to generate a timing signal, during absence of received GPS satellite signals (e.g., during times when less than four satellite signals are received).

Various embodiments of apparatuses and methods for trusted and / or attested packet timestamping are described. In some embodiments, the disclosed system and methods include a reference timekeeper providing a reference clock to host computing devices. The host computing devices host compute instances using a first set of computing resources, and also contain isolated timing hardware utilizing a different set of computing resources. The isolated timing hardware sets a hardware clock based on a signal corresponding to the reference clock from the reference timekeeper. The isolated timing hardware then receives a packet from a particular compute instance, creates a timestamp for the packet based at least in part on the hardware clock, where the timestamp is outside the control of the compute instances, and sends the packet and the timestamp through a data network to transmit to a packet destination.
