Measurement system, measurement method, measurement device, and program

A measurement method, comprising:

• performing measurement a plurality of times on a first basis of a first clock signal having a first clock period to obtain a plurality of measurement results, wherein the first clock signal having the first clock period is oscillated by a first oscillator;
• providing a time stamp indicating a measurement time to each of two or more of the plurality of measurement results obtained through performing the measurement on a second basis of a second clock signal having a second clock period, wherein:
• the second clock signal having the second clock period is oscillated by a second oscillator, and
• the second clock period is longer than the first clock period and has higher accuracy than the first clock period;
• and
• correcting a measurement time of a measurement result other than the measurement result to which the time stamp is provided among the measurement results obtained during a period specified using two time stamps of the time stamps provided to each of the two or more of the plurality of measurement results.

A non-transitory computer readable storage medium storing a program causing a computer which acquires a plurality of measurement results obtained by performing measurement a plurality of times on a first basis of a first clock signal having a first clock period and a time stamp indicating a measurement time provided to each of two or more of the plurality of measurement results on a second basis of a second clock signal having a second clock period, to function as:

• a measurement time correction circuit configured to correct a measurement time of a measurement result other than the measurement result to which the time stamp is provided among the measurement results obtained during a period specified using two time stamps of the time stamps provided to each of the two or more of the plurality of measurement results, in accordance with the period and a number of measurement results obtained during the period among the plurality of measurement results,
• wherein:
• the first clock signal having the first clock period is oscillated by a first oscillator,
• the second clock signal having the second clock period is oscillated by a second oscillator,
• the second clock period is longer than the first clock period, and
• the second clock period has higher accuracy than the first clock period.
