Information processing apparatus and computer program product

摘要

According to an embodiment, an information processing apparatus includes a selector. The selector is configured to acquire a first time obtained by converting a measurement time of a first piece of measurement data based on a clock of a first time server, a second time obtained by converting the measurement time of the first piece of measurement data based on a clock of a second time server, a third time obtained by converting a measurement time of a second piece of measurement data based on the clock of the first time server, and a fourth time obtained by converting the measurement time of the second piece of measurement data based on the clock of the second time server. The selector is also configured to select a time server with the largest number of combinations of the converted times resulting in no error among pieces of measurement data and time servers.

主权项

1. An information processing apparatus, comprising:
a selector configured to
acquire a first converted time obtained by converting a measurement time of a first piece of measurement data on the basis of a clock of a first time server, a second converted time obtained by converting the measurement time of the first piece of measurement data on the basis of a clock of a second time server, a third converted time obtained by converting a measurement time of a second piece of measurement data on the basis of the clock of the first time server, and a fourth converted time obtained by converting the measurement time of the second piece of measurement data on the basis of the clock of the second time server,determine whether an error occurs on the basis of the first, second, third, and fourth converted times,calculate the number of combinations of the first, second, third, and fourth converted times in which it is determined that no error occurs among two or more pieces of measurement data and two or more time servers, andselect a time server with the largest number of combinations.
