The widget is not continuously linked to NIST, it re-synchronizes with NIST every 10 minutes. So the running clock comes from the internal oscillator of the local computer. Therefore, this widget is intended as a time-of-day service only.
It should not be used to make measurements, nor should it be used to establish traceability to NIST.

The widget utilizes the client's computer clock as a timer to measure the round-trip network delay, which is the interval of time starting when the widget sends a time request to the server and ending when the time is displayed in the browser. The time shown estimates that one-half of the round-trip delay is the delay from the time server to the browser.
