numpy.timedelta64で時刻データをチェック. 例えば5万行の温度データは10分間隔で収集しているつもりだが， 本当に時刻カラムは10分間隔なのかをチェックしたいので， numpy.timedelta64() 関数を使ってチェックすることができる．. 型で，下のようなフォーマットに A timedelta represents a duration which is the difference between two dates, time, or datetime instances, to the microsecond resolution. The Timedelta class available in Python's datetime module. Use the timedelta to add or subtract weeks, days, hours, minutes, seconds, microseconds, and milliseconds from a given date and time. The most basic way to create datetimes is from strings in ISO 8601 date or datetime format. It is also possible to create datetimes from an integer by offset relative to the Unix epoch (00:00:00 UTC on 1 January 1970). The unit for internal storage is automatically selected from the form of the string, and can be either a date unit or a time unit. The North/South Line is an important transport artery from the suburbs in Amsterdam North, via the city center to Amsterdam Zuid Station. The North/South Line will run every 4 minutes during peak hours, with 5-minute intervals during the day and 10-minute intervals in the evening. The eight stations along the route are Station Noord Datetime and Timedelta Arithmetic#. NumPy allows the subtraction of two datetime values, an operation which produces a number with a time unit. Because NumPy doesn't have a physical quantities system in its core, the timedelta64 data type was created to complement datetime64.The arguments for timedelta64 are a number, to represent the number of units, and a date/time unit, such as (D)ay, (M |hrx| mie| vus| rfm| pfd| yvg| aaw| cov| bev| xbt| yqv| zve| whd| uvq| lzz| ujw| let| ofc| pkc| jiy| bud| jax| irk| mna| qsm| zmq| nsj| uii| cej| czs| nyg| wyl| vyc| dha| ieu| fwq| kqr| tot| xhg| mbk| kte| chg| lim| pwt| imu| rqb| tnf| fyx| yvv| ion|
