Systems, devices, and methods for more accurately determining a radiopharmaceutical dose administered to a patient by relying on a time factor. Particularly, broadly contemplated herein is the administration of a dose on the basis of an elapsed time from when a dose was last accurately measured in the past to when it is injected into the patient. As such, when a dose is first measured, that timepoint is preferably recorded whereupon the time of injection or administration into a patient is also recorded. Based on the original measured dose, the radionuclide (and thus its known decay rate) and the time elapsed, the dose is calculated and not directly measured on injection. The clocks on the filling station and the transport cart are synchronized to each other or to a known and accepted time standard. In this manner, there is temporal continuity and no inaccuracies of time or loss of time occurs between measurement and injection.

Synchronizing audio and video streams in packet-based networks requires synchronization of packet timestamps. The present invention provides such synchronization without resort to a network time standard. In one embodiment of the present invention, pairs of timestamp synchronized signals, such as audio and video signals, not having a common timestamp clock are mixed. One of the signals, for example, the audio signals, is mixed first while preserving the original audio timestamps. The preserved timestamp information is then used to synchronize the timestamps of the unmixed signals, in this example the video signals, to provide synchronization of all signals. In another embodiment, the present invention uses packets containing calibration of timestamps to reduce jitter. The present invention also includes specifications for a packet for transmitting timestamp information.

A global time reckoning system simultaneously indicates local time and global time. The global time reckoning system can be practiced with standard clock timer drivers, including electromechanical and digital clock motors, in combination with a novel global time system clock face to allow a user to reckon time locally or anywhere on the globe without time zone conversion calculations. The global time system clock face has multiple time scales, at least one of which is driven by the clock drive in cooperation with an hour indicator (e.g., an hour hand). The global time system clock face simultaneously displays global time (relative to any location on the globe) and local time. Additionally, the global time reckoning system, with the appropriate clock timer driver is adaptable to indicate a number of other global time related information, including sunrise / sunset, days of the week, lunar phase and solstices / equinoxes.
