The phrase "a time scale of a" is grammatically correct and can be used in written English.
It can be used when discussing the duration or timeline associated with a particular event, process, or phenomenon.
Example: "The researchers established a time scale of a geological period to better understand the changes in the Earth's climate."
Alternatives: "a timeline of a" or "a duration of a".
Capacitance drifts are observed over a time scale of a few hours at room temperature.
Rats and humans, he said, are divergent in evolution by a time scale of a few hundred million years.
This indicates that even on a time scale of a few years, the ice can respond if deep ocean temperatures drop below or rise above the average.
The lithium ions penetrated into the surface of a LiMn2O4 particle reach to the core with a time scale of a few hours at room temperature.
This observation, together with previous Cerenkov detections, indicates that the high energy emission from Cyg X-3 is evolving on a time scale of a few years which suggests a recent origin for the system in its present form.
